b7f81d372a CMake: don't install tablegen
Since it's an llvm-internal tool, we shouldn't install it.

(This depends on Clang r189127 and lld r189128.)

3eb7322ca1 CMake: build llvm-config on Windows.
It was previously not being built on Windows because the cmake file relied
on a sed script to generate a .in file that llvm-config needs.

By using cmake's configure_file function, we can get rid off the sed hack,
and also have this work on Windows.

ea57433cee Adds cyclic critical path computation and heuristics, temporarily disabled.
Estimate the cyclic critical path within a single block loop. If the
acyclic critical path is longer, then the loop will exhaust OOO
resources after some number of iterations. If lag between the acyclic
critical path and cyclic critical path is longer the the time it takes
to issue those loop iterations, then aggressively schedule for
latency.

it can be overwritten by a nested vararg call, if that happens before va_start.

65ddcfa8c1 [SystemZ] Prefer LHI;ST... over LAY;MV...
If we had a store of an integer to memory, and the integer and store size
were suitable for a form of MV..., we used MV... no matter what.  We could
then have sequences like:

    lay %r2, 0(%r3,%r4)
    mvi 0(%r2), 4

In these cases it seems better to force the constant into a register
and use a normal store:

    lhi %r2, 4
    stc %r2, 0(%r3, %r4)

since %r2 is more likely to be hoisted and is easier to rematerialize.

e0e66b9dfa Update StripDeadDebugInfo to use DebugInfoFinder so that it is no longer stale to the point of not working and more resilient to debug info changes.
The current version of StripDeadDebugInfo became stale and no longer actually
worked since it was expecting an older version of debug info.

This patch updates it to use DebugInfoFinder and the modern DebugInfo classes as
much as possible to make it more redundent to such changes. Additionally, the
only place where that was avoided (the code where we replace the old sets with
the new), I call verify on the DIContextUnit implying that if the format changes
and my live set changes no longer make sense an assert will be hit. In order to
ensure that that occurs I have included a test case.

The actual stripping of the dead debug info follows the same strategy as was
used before in this class: find the live set and replace the old set in the
given compile unit (which may contain dead global variables/functions) with the
new live one.

f1366c5524 DataFlowSanitizer: Prefix the name of each instrumented function with "dfs$".
DFSan changes the ABI of each function in the module.  This makes it possible
for a function with the native ABI to be called with the instrumented ABI,
or vice versa, thus possibly invoking undefined behavior.  A simple way
of statically detecting instances of this problem is to prepend the prefix
"dfs$" to the name of each instrumented-ABI function.

This will not catch every such problem; in particular function pointers passed
across the instrumented-native barrier cannot be used on the other side.
These problems could potentially be caught dynamically.

5f268555b9 Fix ARM vcvt encoding when the number of fractional bits is zero.
The instruction to convert between floating point and fixed point representations
takes an immediate operand for the number of fractional bits of the fixed point
value. ARMARM specifies that when that number of bits is zero, the assembler
should encode floating point/integer conversion instructions. 

This patch adds the necessary instruction aliases to achieve this behaviour.

474be0d0f8 Teach the SLP vectorizer the correct way to check for consecutive access
using GEPs. Previously, it used a number of different heuristics for
analyzing the GEPs. Several of these were conservatively correct, but
failed to fall back to SCEV even when SCEV might have given a reasonable
answer. One was simply incorrect in how it was formulated.

There was good code already to recursively evaluate the constant offsets
in GEPs, look through pointer casts, etc. I gathered this into a form
code like the SLP code can use in a previous commit, which allows all of
this code to become quite simple.

There is some performance (compile time) concern here at first glance as
we're directly attempting to walk both pointers constant GEP chains.
However, a couple of thoughts:

1) The very common cases where there is a dynamic pointer, and a second
   pointer at a constant offset (usually a stride) from it, this code
   will actually not do any unnecessary work.

2) InstCombine and other passes work very hard to collapse constant
   GEPs, so it will be rare that we iterate here for a long time.

That said, if there remain performance problems here, there are some
obvious things that can improve the situation immensely. Doing
a vectorizer-pass-wide memoizer for each individual layer of pointer
values, their base values, and the constant offset is likely to be able
to completely remove redundant work and strictly limit the scaling of
the work to scrape these GEPs. Since this optimization was not done on
the prior version (which would still benefit from it), I've not done it
here. But if folks have benchmarks that slow down it should be straight
forward for them to add.

I've added a test case, but I'm not really confident of the amount of
testing done for different access patterns, strides, and pointer
manipulation.
