ARMMachineFunctionInfo.cpp: Add an initializer of ARMFunctionInfo::ReturnRegsCount in the explicit ctor.

It caused crash since r283867.

llvm-svn: 283908

These were reverted in r283753 and r283747.

The first patch added a header to the root 'Headers' install directory,
instead of into 'Headers/cuda_wrappers'.  This was fixed in the second
patch, but by then the damage was done: The bad header stayed in the
'Headers' directory, continuing to break the build.

We reverted both patches in an attempt to fix things, but that still
didn't get rid of the header, so the Windows boostrap build remained
broken.

It's probably worth fixing up our cmake logic to remove things from the
install dirs, but in the meantime, re-land these patches, since we
believe they no longer have this bug.

Summary:
This test is allowed to run on non-x86 hosts and thus must use
llvm-nm rather than nm.

The non-obvious motivation for adding this fold (which already happens in InstCombine)
is that we want to canonicalize IR towards select instructions and canonicalize DAG 
nodes towards boolean math. So we need to recreate some folds in the DAG to handle that
change in direction. 

An interesting implementation difference for cases like this is that InstCombine
generally works top-down while the DAG goes bottom-up. That means we need to detect 
different patterns. In this case, the SimplifyDemandedBits fold prevents us from 
performing a zext to sext fold that would then be recognized as a negation of a sext.

A recent change to llvm::cl slightly changed the format of

Previously we would print

  USAGE: <exe> [subcommand] [options]

Even if no subcommands were present.  This changes the output
format to only print "[subcommand]" if there is at least one
subcommand.

Fixes llvm.org/pr30598

Patch by Serge Guelton

llvm-svn: 283892

Currently Clang allows partial initializer for C99 but not for OpenCL, e.g.

float a[16][16] = {1.0f, 2.0f};

is allowed in C99 but not allowed in OpenCL.

This patch fixes that.

MSVC does not like the declaration of a terminate() function (I guess it looks
too much like std::terminate()). While I'm there, move the setup/teardown code
into the functions gtest provides for that purpose.

Summary:
Only member initializers that are written should prevent
