8d1cf2218d Use a specified list of languages in cmake project() command.
This allows asm files and Cxx files to be compiled with different flags
rather than treating them identically. LLVM itself has no asm files
other than tests, but this setting is inherited by the compiler-rt
project (unless compiled standalone), which does have asm files.

3b948587b2 [GMR] Teach GlobalsModRef to distinguish an important and safe case of
no-alias with non-addr-taken globals: they cannot alias a captured
pointer.

If the non-global underlying object would have been a capture were it to
alias the global, we can firmly conclude no-alias. It isn't reasonable
for a transformation to introduce a capture in a way observable by an
alias analysis. Consider, even if it were to temporarily capture one
globals address into another global and then restore the other global
afterward, there would be no way for the load in the alias query to
observe that capture event correctly. If it observes it then the
temporary capturing would have changed the meaning of the program,
making it an invalid transformation. Even instrumentation passes or
a pass which is synthesizing stores to global variables to expose race
conditions in programs could not trigger this unless it queried the
alias analysis infrastructure mid-transform, in which case it seems
reasonable to return results from before the transform started.

See the comments in the change for a more detailed outlining of the
theory here.

This should address the primary performance regression found when the
non-conservatively-correct path of the alias query was disabled.

d6254520cd Improving lli documentation
Too many people hope lli would act as an emulator when it's actually
just a tool to help prototype IR code and test the JIT compiler. This
commit makes that fact explicit in the documentation

It also migrates the old style bold/italic doc tags to the preferred
meta tags (.. option::, :program:, etc).

No errors when generating the documents, visual inspection in the HTML
result doesn't show any major difference, apart from the slight style
change.

89576cea3f [GMR] Fix a long-standing bug in GlobalsModRef where it failed to clear
out the per-function modref data structures when functions were deleted
or when globals were deleted.

I don't actually know how the global deletion side of this bug hasn't
been hit before, but for the other it just-so-happens that functions
aren't likely to be deleted in the particular part of the LTO pipeline
where we currently enable GMR, so we got lucky.

With this patch, I can self-host with GMR enabled in the normal pass
pipeline!

I was a bit concerned about the compile-time impact of this chang, which
is part of what motivated my prior string of patches to make the
per-function datastructure very dense and fast to walk. With those
changes in place, I can't measure a significant compile time difference
(the difference is around 0.1% which is *way* below the noise) before
and after this patch when building a linked bitcode for all of Clang.

bd426c622e [LDist][LVer] Explicitly pass the set of memchecks to LoopVersioning, NFC
Before the patch, the checks were generated internally in
addRuntimeCheck.  Now, we use the new overloaded version of
addRuntimeCheck that takes the ready-made set of checks as a parameter.

The checks are now generated by the client (LoopDistribution) with the
new RuntimePointerChecking::generateChecks API.

Also the new printChecks API is used to print out the checks for
debugging.

This is to continue the transition over to the new model whereby clients
will get the full set of checks from LAA, filter it and then pass it to
LoopVersioning and in turn to addRuntimeCheck.

b25dcfd104 Reserve some constant values for the Swift calling convention.
Swift has a custom calling convention that also requires some new flags
on arguments and one new attribute on alloca instructions. This patch
does not include the implementation of that calling convention - that
will be provided as part of the open-source release of Swift; this only
reserves the bitcode constant values so that they are not used for
other purposes.

3d89ab8299 fix invalid load folding with SSE/AVX FP logical instructions (PR22371)
This is a follow-up to the FIXME that was added with D7474 ( http://reviews.llvm.org/rL229531 ).
I thought this load folding bug had been made hard-to-hit, but it turns out to be very easy
when targeting 32-bit x86 and causes a miscompile/crash in Wine:
https://bugs.winehq.org/show_bug.cgi?id=38826
https://llvm.org/bugs/show_bug.cgi?id=22371#c25

The quick fix is to simply remove the scalar FP logical instructions from the load folding table
in X86InstrInfo, but that causes us to miss load folds that should be possible when lowering fabs,
fneg, fcopysign. So the majority of this patch is altering those lowerings to use *vector* FP
logical instructions (because that's all x86 gives us anyway). That lets us do the load folding 
legally.

04180d08db [opaque pointer type] Avoid using pointee types to retrieve InlineAsm's function type
As a stop-gap, retrieving the InlineAsm's function type was done via the
pointee type of its (pointer) Value type.

Instead, pass down and store the FunctionType in the InlineAsm object.

The only wrinkle with this is the ConstantUniqueMap, which then needs to
ferry the FunctionType down through the InlineAsmKeyType. This could be
done a bit differently if the ConstantInfo trait were broadened a bit to
provide an extension point for access to the TypeClass object from the
ValType objects, so that the ConstantUniqueMap<InlineAsm> would then be
keyed on FunctionTypes instead of PointerTypes that point to
FunctionTypes.

This drops the number of IR tests that don't roundtrip through bitcode*
without calling PointerType::getElementType from 416 to 8 (out of
10733). 3 of those crash when roundtripping at ToT anyway.

* modulo various unavoidable uses of pointer types when validating IR
  (for now) and in the way globals are parsed, unfortunately. These
  cases will either go away (because such validation will no longer be
  necessary or possible when pointee types are opaque), or have to be
  made simultaneously with the removal of pointee types.

2261a25f88 [LAA] Split out a helper to print a collection of memchecks
This is effectively an NFC but we can no longer print the index of the
pointer group so instead I print its address.  This still lets us
cross-check the section that list the checks against the section that
list the groups (see how I modified the test).

E.g. before we printed this:

    Run-time memory checks:
    Check 0:
      Comparing group 0:
        %arrayidxC = getelementptr inbounds i16, i16* %c, i64 %store_ind
        %arrayidxC1 = getelementptr inbounds i16, i16* %c, i64 %store_ind_inc
      Against group 1:
        %arrayidxA = getelementptr i16, i16* %a, i64 %ind
        %arrayidxA1 = getelementptr i16, i16* %a, i64 %add
    ...
    Grouped accesses:
      Group 0:
        (Low: %c High: (78 + %c))
          Member: {%c,+,4}<%for.body>
          Member: {(2 + %c),+,4}<%for.body>

Now we print this (changes are underlined):

    Run-time memory checks:
    Check 0:
      Comparing group (0x7f9c6040c320):
                       ~~~~~~~~~~~~~~
        %arrayidxC1 = getelementptr inbounds i16, i16* %c, i64 %store_ind_inc
        %arrayidxC = getelementptr inbounds i16, i16* %c, i64 %store_ind
      Against group (0x7f9c6040c358):

4f7a4bc79f [opaque pointers] Avoid the use of pointee types when parsing inline asm in IR
When parsing calls to inline asm the pointee type (of the pointer type
representing the value type of the InlineAsm value) was used. To avoid
using it, use the ValID structure to ferry the FunctionType directly
through to the InlineAsm construction.

This is a bit of a workaround - alternatively the inline asm could
explicitly describe the type but that'd be verbose/redundant in the IR
and so long as the inline asm calls directly in the context of a call or
invoke, this should suffice.

39d6da003d [IndVars] Make loop varying predicates loop invariant.
Summary:
Was D9784: "Remove loop variant range check when induction variable is
strictly increasing"

This change re-implements D9784 with the two differences:

 1. It does not use SCEVExpander and does not generate new
    instructions.  Instead, it does a quick local search for existing
    `llvm::Value`s that it needs when modifying the `icmp`
    instruction.

 2. It is more general -- it deals with both increasing and decreasing
    induction variables.

I've added all of the tests included with D9784, and two more.

As an example on what this change does (copied from D9784):

Given C code:

```
for (int i = M; i < N; i++) // i is known not to overflow
  if (i < 0) break;
  a[i] = 0;
}
```

This transformation produces:

```
for (int i = M; i < N; i++)
  if (M < 0) break;
  a[i] = 0;
}
```

Which can be unswitched into:

```
if (!(M < 0))
  for (int i = M; i < N; i++)
    a[i] = 0;
}
```

I went back and forth on whether the top level logic should live in
`SimplifyIndvar::eliminateIVComparison` or be put into its own
routine.  Right now I've put it under `eliminateIVComparison` because
even though the `icmp` is not *eliminated*, it no longer is an IV
comparison.  I'm open to putting it in its own helper routine if you
think that is better.

6e208e96cc [AArch64] Remove check for Darwin that was needed to decide if x18 should
be reserved.

The decision to reserve x18 is going to be made solely by the front-end,
so it isn't necessary to check if the OS is Darwin in the backend.
