bd1729e5d4 [X86][FastIsel] Avoid introducing legacy SSE instructions if the target has AVX.
This patch teaches X86FastISel how to select AVX instructions for scalar
float/double convert operations.

Before this patch, X86FastISel always selected legacy SSE instructions
for FPExt (from float to double) and FPTrunc (from double to float).

For example:
\code
  define double @foo(float %f) {
    %conv = fpext float %f to double
    ret double %conv
  }
\end code

Before (with -mattr=+avx -fast-isel) X86FastIsel selected a CVTSS2SDrr which is
legacy SSE:
  cvtss2sd %xmm0, %xmm0

With this patch, X86FastIsel selects a VCVTSS2SDrr instead:
  vcvtss2sd %xmm0, %xmm0, %xmm0

Added test fast-isel-fptrunc-fpext.ll to check both the register-register and
the register-memory float/double conversion variants.

3e77df419d Revert r228556: InstCombine: propagate nonNull through assume
This commit isn't using the correct context, and is transfoming calls
that are operands to loads rather than calls that are operands to an
icmp feeding into an assume. I've replied on the original review thread
with a very reduced test case and some thoughts on how to rework this.

e65664e90d [Orc] Fix a bug in the LazyEmittingLayer - capture names by value (as
std::strings) rather than StringRefs in JITSymbol get-address lambda.

Capturing a StringRef by-value is still effectively capturing a reference, which
is no good here because the referenced string may be gone by the time the lambda
is being evaluated the original value may be gone. Make sure to capture a
std::string instead.

No test case: This bug doesn't manifest under OrcMCJITReplacement, since it
keeps IR modules (from which the StringRefs are sourced) alive permanently.

afd23204f0 Teach llvm_add_library() to find include dirs.
Since header files are not compilation units, CMake does not require
you to specify them in the CMakeLists.txt file.  As a result, unless a
header file is explicitly added, CMake won't know about it, and when
generating IDE-based projects, CMake won't put the header files into
the IDE project.  LLVM currently tries to deal with this in two ways:

  1) It looks for all .h files that are in the project directory, and
     adds those.
  2) llvm_add_library() understands the ADDITIONAL_HEADERS argument,
     which allows one to list an arbitrary list of headers.

This patch takes things one step further.  It adds the ability for
llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which
will specify a list of folders which CMake will glob for header files.
Furthermore, it will glob not only for .h files, but also for .inc
files.

Included in this CL is an update to one of the existing users of
ADDITIONAL_HEADERS to use this new argument instead, to serve as an
illustration of how this cleans up the CMake.

The big advantage of this new approach is that until now, there was no
way for the IDE projects to locate the header files that are in the
include tree.  In other words, if you are in, for example,
lib/DebugInfo/DWARF, the corresponding includes for this project will
be located under include/llvm/DebugInfo/DWARF.  Now, in the
CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write:

  ADDITIONAL_HEADER_DIRS
  ../../include/llvm/DebugInfo/DWARF

as an argument to llvm_add_library(), and all header files will get
added to the IDE project.

1c7c2e8650 [x86] Fix PR22524: the DAG combiner was incorrectly handling illegal
nodes when folding bitcasts of constants.

We can't fold things and then check after-the-fact whether it was legal.
Once we have formed the DAG node, arbitrary other nodes may have been
collapsed to it. There is no easy way to go back. Instead, we need to
test for the specific folding cases we're interested in and ensure those
are legal first.

This could in theory make this less powerful for bitcasting from an
integer to some vector type, but AFAICT, that can't actually happen in
the SDAG so its fine. Now, we *only* whitelist specific int->fp and
fp->int bitcasts for post-legalization folding. I've added the test case
from the PR.

(Also as a note, this does not appear to be in 3.6, no backport needed)

Win64 has specific contraints on what valid prologues and epilogues look

Prologues previously emitted by LLVM could not be represented by the

successfully work.

to make those changes promptly after this hierarchy is moved underneath
`DIDescriptor`, but for now I'm aiming mostly to match the status quo.

2fc495a300 Adjust how we avoid poll insertion inside the poll function (NFC)
I realized that my early fix for this was overly complicated.  Rather than scatter checks around in a bunch of places, just exit early when we visit the poll function itself.

Thinking about it a bit, the whole inlining mechanism used with gc.safepoint_poll could probably be cleaned up a bit.  Originally, poll insertion was fused with gc relocation rewriting.  It might be worth going back to see if we can simplify the chain of events now that these two are seperated.  As one thought, maybe it makes sense to rewrite calls inside the helper function before inlining it to the many callers.  This would require us to visit the poll function before any other functions though..

ba59efdfc8 isDereferenceablePointer: look through gc.relocate calls
While a theoretical GC might change dereferenceability on collection,
there is no such known collector and no need to account for the case
with a flag yet.

ea280d963d Reduce the LockFileManager timeout, and provide unsafeRemoveLockFile
5 minutes is an eternity, so try to strike a better balance between
waiting long enough for any reasonable module build and not so long that
users kill the process because they think it's hanging.

Also give the client a way to delete the lock file after a timeout.
