5deb1bf97f Support: Add *cast_or_null<> for pointer wrappers
Fill in omission of `cast_or_null<>` and `dyn_cast_or_null<>` for types
that wrap pointers (e.g., smart pointers).

Type traits need to be slightly stricter than for `cast<>` and
`dyn_cast<>` to resolve ambiguities with simple types.

There didn't seem to be any unit tests for pointer wrappers, so I tested
`isa<>`, `cast<>`, and `dyn_cast<>` while I was in there.

This only supports pointer wrappers with a conversion to `bool` to check
for null.  If in the future it's useful to support wrappers without such
a conversion, it should be a straightforward incremental step to use the
`simplify_type` machinery for the null check.  In that case, the unit
tests should be updated to remove the `operator bool()` from the
`pointer_wrappers::PTy`.

88dc43f69e Remove support for undocumented SpecialCaseList entries.
"global-init", "global-init-src" and "global-init-type" were originally
used to blacklist entities in ASan init-order checker. However, they
were never documented, and later were replaced by "=init" category.

Old blacklist entries should be converted as follows:
  * global-init:foo -> global:foo=init
  * global-init-src:bar -> src:bar=init
  * global-init-type:baz -> type:baz=init

58c62e1dba [ADT] Fix PR20728 - Incorrect APFloat::fusedMultiplyAdd results for x86_fp80.
As detailed at http://llvm.org/PR20728, due to an internal overflow in
APFloat::multiplySignificand the APFloat::fusedMultiplyAdd method can return
incorrect results for x87DoubleExtended (x86_fp80) values. This commonly
manifests as incorrect constant folding of libm fmal calls on x86. E.g.

fmal(1.0L, 1.0L, 3.0L) == 0.0L      (should be 4.0L)

This patch fixes PR20728 by adding an extra bit to the significand for
intermediate results of APFloat::multiplySignificand, avoiding the overflow.

1d4f28c6bc Remove StringMap::GetOrCreateValue in favor of StringMap::insert
Having two ways to do this doesn't seem terribly helpful and
consistently using the insert version (which we already has) seems like
it'll make the code easier to understand to anyone working with standard
data structures. (I also updated many references to the Entry's
key and value to use first() and second instead of getKey{Data,Length,}
and get/setValue - for similar consistency)

Also removes the GetOrCreateValue functions so there's less surface area
to StringMap to fix/improve/change/accommodate move semantics, etc.

038e20451d Improve long path name support on Windows.
Windows normally limits the length of an absolute path name to 260
characters; directories can have lower limits.  These limits increase
to about 32K if you use absolute paths with the special '\\?\'
prefix. Teach Support\Windows\Path.inc to use that prefix as needed.

TODO: Other parts of Support could also learn to use this prefix.

2217648f91 [Bitcode] AtEndOfStream should only check against the size if it's known.

(In the rare case that the size is known and actually 0, the slow path will still
handle it correctly.)

d9078385de Ensure function_refs are copyable even from non-const references
A subtle bug was found where attempting to copy a non-const function_ref
lvalue would actually invoke the generic forwarding constructor (as it
was a closer match - being T& rather than the const T& of the implicit
copy constructor). In the particular case this lead to a dangling
function_ref member (since it had referenced the function_ref passed by
value to its ctor, rather than the outer function_ref that was still
alive)

SFINAE the converting constructor to not be considered if the copy
constructor is available and demonstrate that this causes the copy to
refer to the original functor, not to the function_ref it was copied
from. (without the code change, the test would fail as Y would be
referencing X and Y() would see the result of the mutation to X, ie: 2)

c35c39b73c Remove the PreserveSource linker mode.
I noticed that it was untested, and forcing it on caused some tests to fail:

    LLVM :: Linker/metadata-a.ll
    LLVM :: Linker/prefixdata.ll
    LLVM :: Linker/type-unique-odr-a.ll
    LLVM :: Linker/type-unique-simple-a.ll
    LLVM :: Linker/type-unique-simple2-a.ll
    LLVM :: Linker/type-unique-simple2.ll
    LLVM :: Linker/type-unique-type-array-a.ll
    LLVM :: Linker/unnamed-addr1-a.ll
    LLVM :: Linker/visibility1.ll

If it is to be resurrected, it has to be fixed and we should probably have a
-preserve-source command line option in llvm-mc and run tests with and without
it.

950c6482c6 [MCJIT] Make repeat calls to MCJIT::getPointerToFunction for declarations safe.
MCJIT::getPointerForFunction adds the resulting address to the global mapping.
This should be done via updateGlobalMapping rather than addGlobalMapping, since
the latter asserts if a mapping already exists.

MCJIT::getPointerToFunction is actually deprecated - hopefully we can remove it
(or more likely re-task it) entirely soon. In the mean time it should at least
work as advertised.

This reverts commit r218918, effectively reapplying r218914 after fixing
an Ocaml bindings test and an Asan crash.  The root cause of the latter
was a tightened-up check in `DILexicalBlock::Verify()`, so I'll file a
PR to investigate who requires the loose check (and why).

Original commit message follows.

This patch addresses the first stage of PR17891 by folding constant
arguments together into a single MDString.  Integers are stringified and
a `\0` character is used as a separator.

Part of PR17891.

Note: I've attached my testcases upgrade scripts to the PR.  If I've
just broken your out-of-tree testcases, they might help.
