NOTE: reverts r242077 to reinstate r242058, r242065, 242067
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.

The tests were failing on OS X.
Revert "[cuda] Driver changes to compile and stitch together host and device-side CUDA code."
Revert "Fixed regex to properly match '64' in the test case."
Revert "clang/test/Driver/cuda-options.cu REQUIRES clang-driver, at least."

This patch adds support for specifying where the profile is emitted in a
way similar to GCC. These flags are used to specify directories instead
of filenames. When -fprofile-generate=DIR is used, the compiler will
generate code to write to <DIR>/default.profraw.
The patch also adds a couple of extensions: LLVM_PROFILE_FILE can still be
used to override the directory and file name to use and -fprofile-use
accepts both directories and filenames.
To simplify the set of flags used in the backend, all the flags get
canonicalized to -fprofile-instr-{generate,use} when passed to the
backend. The decision to use a default name for the profile is done
in the driver.

For Mips direct-to-nacl, the goal is to be close to le32 front-end and
use Mips32EL backend. This patch defines new NaClMips32ELTargetInfo and
modifies it slightly to be close to le32. It also adds necessary parts,
inline with ARM and X86.

This re-commits r226005 with a tweak. The origin attempt failed because
Darwin bot sets up SDKROOT and clang can deduce SDK version from them
after this patch. That broke many driver tests due to the change of
deployment target version. Now the tests should not complain after
r240574.

Classes in Tools.h inherit ultimately from Tool, which is a noun,
but subclasses of Tool were named for their operation, such as "Compile",
wherein the constructor call "Compile(args...)" could be misconstrued
as actually causing a compile to happen.
Likewise various other methods were not harmonious with their effect,
in that "BuildLinker()" returned a "new namespace::Link(...)"
instead of a "new namespace::Linker(...)" which it now does.
Exceptions: Clang and ClangAs are un-renamed. Those are their rightful names.
And there is no particulary great way to name the "Lipo-er" and a few others.

Introduce ToolChain::getSupportedSanitizers() that would return the set
of sanitizers available on given toolchain. By default, these are
sanitizers which don't necessarily require runtime support and are
not toolchain- or architecture-dependent.
Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function
without runtime library are marked as supported only on platforms
for which we actually build these runtimes.
This would allow more fine-grained checks in the future: for instance,
we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+
(PR23539).
Update test cases accrodingly: add tests for certain unsupported
configurations, remove test cases for -fsanitize=vptr + PS4
integration, as we don't build the runtime for PS4 at the moment.
This change was first submitted as r239953 and reverted in r239958.
The problem was and still is in Darwin toolchains, which get the
knowledge about target platform too late after initializaition, while
now we require this information when ToolChain::getSanitizerArgs() is
called. r240170 works around this issue.

This change passes through C and assembler jobs to Movidius tools by
constructing commands which are the same as ones produces by the examples
in the SDK. But rather than reference MV_TOOLS_DIR to find tools,
we will assume that binaries are installed wherever the Driver would
find its native tools. Similarly, this change assumes that -I options
will "just work" based on where SDK headers get installed, rather than
baking into the Driver some magic paths.

Adds tests verifying the proper dirs are found in the Debian 8/GCC4.9
layout for sparc (32bit), sparc (32bit) with lib64 multilib, and

The test cases added here also cover r239047, which fixed the linker
paths.

The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.

Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib
shouldn't prevent it from being linked. This makes Darwin behave like
other toolchains, and link in the profile runtime irrespective of
-nostdlib, since the resulting program can't be run unless you link
this.
I've also added a test to show that other toolchains already behave
like this.

This is a starting point for using the TargetParser in Clang, in a simple
enough part of the code that can be used without disrupting the crazy
platform support that we need to be compatible with other toolchains.
Also adding a few FIXME on obvious places that need replacing, but those
cases will indeed break a few of the platform assumptions, as arch/cpu names
change multiple times in the driver.
Finally, I'm changing the "neon-vfpv3" behaviour to match standard NEON, since
-mfpu=neon implies vfpv3 by default in both Clang and LLVM. That option
string is still supported as an alias to "neon".

This change is the third of 3 patches to add support for specifying
the profile output from the command line via -fprofile-instr-generate=<path>,
where the specified output path/file will be overridden by the
LLVM_PROFILE_FILE environment variable.
This patch adds the necessary support to the clang frontend, and adds a
new test.
The compiler-rt and llvm parts are r236055 and r236288, respectively.

Summary:
Change the way we use ASan and UBSan together. Instead of keeping two
separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan
into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on
a platform, all UBSan sources are just compiled into dummy empty object
files. UBSan initialization code (e.g. flag parsing) is directly called
from ASan initialization, so we are able to enforce correct
initialization order.
This mirrors the approach we already use for ASan+LSan. This change doesn't
modify the way we use standalone UBSan.

Add Tool and ToolChain support for clang to target the NaCl OS using the NaCl
SDK for x86-32, x86-64 and ARM.
Includes nacltools::Assemble and Link which are derived from gnutools. They
are similar to Linux but different enought that they warrant their own class.
Also includes a NaCl_TC in ToolChains derived from Generic_ELF with library
and include paths suitable for an SDK and independent of the system tools.

Now that CloudABI's target information and header search logic for Clang
has been submitted, the only thing that remains to be done is adding
support for CloudABI's linker.
CloudABI uses Binutils ld, although there is some work to use lld
instead. This means that this code is largely based on what we use on
FreeBSD. There are some exceptions, however:
- Only static linking is performed. CloudABI does not support any
dynamically linked executables.
- CloudABI uses compiler-rt, libc++ and libc++abi unconditionally. Link
in these libraries instead of using libgcc_s, libstdc++, etc.
- We must ensure that the .eh_frame_hdr is present to make C++
exceptions work properly.

Summary:
UBSan is now used in the same way as ASan, and is supported on

together due to PR21112, but I hope to resolve it soon by
embedding UBSan into ASan.
