This patch allows Clang to pass on -Wa,-mfpu, -Wa,-mhwdiv and
-Wa,-mcpu to the integrated assembler (via target-features), but
-march is still not being passed, but validated.
In case the command line has both -mxxx and -Wa,-mxxx, we warn
that the naked one will not be used in assembler mode.

Currently trigger to select hard-float linker is only based of -gnueabihf
appearing in target triplet, but we should also select it when hardfloat
is requested via cmdline.

We had multiple bugs here:
- We didn't support multiple optimization options in one argument.
e.g. -O2y-
- We didn't correctly expand -O[12dx] to their respective options.
- We treated -O1 as clang -O1 instead of clang -Os.
- We treated -Ox as clang -O3 instead of clang -O2. In fact, cl's -Ox
option is *less* powerful than cl's -O2 option despite -Ox described
as "Full Optimization".
This fixes PR24003.

This is a follow-up to r243185, which made changes to pass subtarget

The flag allows users to specify that they do not want the object file

Currently, for --rtlib=compiler-rt on GNU systems, we're assuming
that one has libgcc_s and libgcc_eh as low-level libraries, which
when used in conjunction with -lunwind or -lc++abi, breaks that
assumption.
My original fix was wrong, and this patch reverts it to prepare for
a new flag to choose the unwinder/C++ libraries. For the time being,
people can use "-lgcc_s -lgcc_eh" or "-lunwind -lc++abi" or any
combination they need explicitly.

option "-arm-reserve-r9".
This recommits r242736, which had to be reverted because the llvm-side
change that was committed in r242737 caused the number of subtarget
features to go over the limit of 64.
This change is needed since backend options do not make it to the backend
when doing LTO and are not capable of changing the behavior of code-gen
passes on a per-function basis.

Currently, -save-temp will cause ObjCARC optimization to be dropped,
sanitizer pass to run early in the pipeline, and profiling
instrumentation to run twice.
Fix the issue by properly disable all passes in the optimization
pipeline when generating bitcode output and parse some of the Language
Options even when the input is bitcode so the passes can be setup
correctly.

We were still using the Unix response file tokenizer for all driver
modes. This was difficult to get right in the beginning because there is
a circular dependency. The Driver class also can't officially determine
its mode until it can see all possible --driver-mode= flags, and those
flags could come from the response file.
Now we use the Windows parsing algorithm if the program name looks like
clang-cl, or if the --driver-mode=cl flag is present on the main command
line.
Fixes PR23709.

is true on MSYS bash although this requires: used to disable tests on MSYS bash.
Nevertheless, all tests requiring shell-preserves-root do pass except for
Driver/darwin-sdkroot.c. It will require a patch, either by disabling it on
Windows or by fixing shell-preserves-root to really be true only on MSYS
and making darwin-sdkroot.c its only user.
In any case, all other tests requiring shell-preserves-root do not really require
it so I'm replacing REQUIRES: shell-preserves-root with REQUIRES: shell in two
tests first.

Rather than making -fexceptions a core option that enables C++ EH in
clang-cl, users can use the '-Xclang -fexceptions -Xclang
-fcxx-exceptions' flag set. We weren't going to expose -fexceptions in
clang-cl in the long run, so this way we don't add and then remove a
flag.

and includes fix for OS X test failures.
- Changed driver pipeline to compile host and device side of CUDA
files and incorporate results of device-side compilation into host
object file.
- Added a test for cuda pipeline creation in clang driver.
New clang options:
--cuda-host-only - Do host-side compilation only.
--cuda-device-only - Do device-side compilation only.
--cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side
compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more
than once in which case one device-compilation will be done per
unique specified GPU architecture.

We don't need any more bug reports from users telling us that MSVC-style
C++ exceptions are broken. Developers and adventurous users can still
test the existing functionality by passing along -fexceptions to either
clang or clang-cl.

All of the ABIs we support are altivec style anyhow and so the option
doesn't make much sense with the modern ABIs. We could make this a more
noisy ignore, but it would break builds for projects that just pass
it along by default because of historical reasons.
