Summary:
CUDA 7.0's libdevice uses slightly different IR to call __nvvm_reflect
and that triggers an assertion in nvvm_reflect optimization pass. This
change allows nvvm_reflect pass to deal with both old and new ways to
pass an argument to __nvvm_reflect.

The dependencies for cross-built tablegen were a bit confused. This fixes that. The following dependencies are now enforced:
(1) Tablegen tasks depend on the native tablegen
(2) Native tablegen depends on the cross-compiled tablegen
Although the native tablegen doesn't actually require the cross tablegen, having this dependency forces the native tablegen to rebuild whenever the cross tablegen changes.

NFC currently but required as a prerequisite for using
the Microsoft resource compiler in conjunction with
CMake's ninja generator, which knows how to filter flags
appropriately, but not definitions.

This is an ugly hack to fix the configure --enable-shared build. It
turns out that *every cl::opt in LLVM* shows up in *every tool* in
that configuration, which is hopelessly broken. This skirts around the
issue by not colliding with another option's name, for now.
I've also simplified the option implementation - the other "color"
option used cl::boolOrDefault and was much nicer than what I'd written
before.

There are two main advantages to doing this
* Targets that only need to handle one of the formats specially don't have
to worry about the others. For example, x86 now only registers a
constructor for the COFF streamer.
* Changes to the arguments passed to one format constructor will not impact
the other formats.

The clang-hexagon elf bot was complaining that "Option 'color'
registered more than once!":
http://lab.llvm.org:8011/builders/clang-hexagon-elf/builds/24425
I don't understand why this error is happening, and I don't see it on
any other bots or on my own machine, so I'm kind of grasping at
straws. Try using an unscoped enum and specifying a cl::init to see if
they help.

From what I can tell, the code is checking for PHIs that expect any value from
this block, not just constants.

Some subregisters are only to indicate different access sizes, while not
providing any way to actually divide the register up into multiple
disjunct parts. Avoid tracking subregister liveness in these cases as it
is not beneficial.

This replaces the -no-color flag with a -color={auto|always|never}
option, with auto as the default, which is much saner.

This should bring the windows bots back.
It is a bit ugly, but it is better than what we had before: The triple would
say that the object format was COFF, but llc/llvm-mc would produce an ELF.

Summary:
This change makes CMake scan for lit suites and generate a target for each lit test suite. The targets follow the format check-<project>-<suite path>.
For example:
check-llvm-unit - Runs the LLVM unit tests
check-llvm-codegen-arm - Runs the ARM codeine tests
Note: These targets are not generated during multi-configuration generators (i.e. Xcode and Visual Studio) because target clutter impacts UI usability.

as we don't necessarily need to do this yet - though we could move
the base class to the TargetMachine as it isn't subtarget dependent.
This reverts commit r232103.

The MSVC linker won't produce a .lib file for an executable that doesn't
export anything, and LLVM doesn't maintain dllexport annotations or .def
files listing all C++ symbols. It also doesn't support exporting all
symbols, like binutils ld.
CMake 3.2 changed the Ninja generator to list both the .exe and .lib
files as outputs of executable build targets. Ninja would always re-link
executables with ENABLE_EXPORTS because the .lib output file was not
present, and therefore the target was out of date.

Currently v2i64 vectors shifts (non-equal shift amounts) are scalarized, costing 4 x extract, 2 x x86-shifts and 2 x insert instructions - and it gets even more awkward on 32-bit targets.
This patch separately shifts the vector by both shift amounts and then shuffles the partial results back together, costing 2 x shuffles and 2 x sse-shifts instructions (+ 2 movs on pre-AVX hardware).
Note - this patch only improves the SHL / LSHR logical shifts as only these are supported in SSE hardware.

When calculating the lanemask of a register class we have to include the
masks of subregisters supported by any of the class members, not just
the ones supported by all class members.
This fixes problems when coalescing towards a subclass with additional
subregisters available.
The attached testcase works fine as is, but does crash if you enable
subregister liveness on x86 without this change applied.

The checks here were so vague that we could nuke intrinsics
from existence and still pass the test because we'd match
the function name.

The 'vmovntdq' was only passing due to a fluke in
SandyBridge codegen that splits 32-byte stores in half,
but that meant that the test was not correctly checking
for the 32-byte store that we thought we were generating.
The lax checking in this file will be addressed in
another commit. There are bigger problems here.
