Various bits we'd like to use the new ABI actually compile with "-arch armv7k
-miphoneos-version-min=9.0". Not ideal, but also not ridiculous given how
slices work.

This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html

Support for the -fno-math-builtin option was added in r186899. The codegen side
is being tested in test/CodeGen/nomathbuiltin.c. The missing part was just
passing the option through the driver.

* Runtime diagnostic data for cfi-icall changed to match the rest of
cfi checks
* Layout of all CFI diagnostic data changed to put Kind at the
beginning. There is no ABI stability promise yet.
* Call cfi_slowpath_diag instead of cfi_slowpath when needed.
* Emit __cfi_check_fail function, which dispatches a CFI check
faliure according to trap/recover settings of the current module.
* A tiny driver change to match the way the new handlers are done in
compiler-rt.

Summary:
MSVC's driver accepts all unknown arguments but warns about them. clang
by default rejects all unknown arguments. This causes issues
specifically with build systems such as autoconf which liberally pass
things such as $LDFLAGS to the compiler and expect everything to work.
This patch teaches clang-cl to ignore unknown driver arguments.

-fsplit-stack should pass --wrap=pthread_create to linker for -fsplit-stack
It is needed to initialize the stack guard. This fixes PR 20148.

Microsoft's documentation states that specifying
/Oy- after the /O[12x] options disables frame-pointer omission.
What it does *not* state is that it also disables frame-pointer omission
if /Oy- is specified before /O[12x].

Many of the "unix" checkers are not actually unix-specific and would be valuable
to run on Windows. This commit explicitly enables those checkers on
Windows.

Summary:
It's possible to BindArch without changing the toolchain at all. For
example, armv7 and armv7s have exactly the same toolchain triple.
Therefore the code in the Driver that checks that we're not creating a
job for the same Action twice needs to consider (Action, Toolchain,
BoundArch) tuples.

Summary:
Previously we compiled CUDA device code to PTX assembly and embedded
that asm as text in our host binary. Now we compile to PTX assembly and
then invoke ptxas to assemble the PTX into a cubin file. We gather the
ptx and cubin files for each of our --cuda-gpu-archs and combine them
using fatbinary, and then embed that into the host binary.
Adds two new command-line flags, -Xcuda_ptxas and -Xcuda_fatbinary,
which pass args down to the external tools.

Summary:
Right now if the Action graph is a DAG and we encounter an action twice,
we will run it twice.
This patch is difficult to test as-is, but I have testcases for this as
used within CUDA compilation.

The PIC default is set for the MachO toolchain, not just the Darwin toolchain,
so this treats those the same. The behavior with -static should be the same
for all MachO targets. rdar://24152327

There was a thinko in the deployment target detection code that
made the -isysroot parsing have precedence over the environment
variable for tvOS. This patch makes this logic symetric for all
platforms (the env variable must have precedence).

Will re-apply after llvm 3.8 is branched.
Original commit message:
Driver: fallback to the location of clang if no sysroot,
hard coding /usr makes little sense for mingw-w64.
If we have portable toolchains having /usr breaks that.
If the clang we use is in /usr/bin or /usr/sbin etc this will
still detect as though it was hard coded to /usr
This makes the most sense going forward for mingw-w64 toolchains
on both linux and mac
llvm-svn: 257468
Summary:
The CUDA toolchain needs to know which Actions created which InputInfos,
because it needs to attach GPU archs to the various InputInfos.

Summary:
In rL256641, @davide turned off movt generation by default for FreeBSD.
This was because our ld is very old, and did not support the relocations
for it. However, Ian Lepore added the support very recently, so we
would like to revert rL256641, and replace it with a new `-fno-movt`
frontend option. This way, it can be turned off when needed.

A gcc tool has an "integrated" assembler (usually gas) that it
will call to produce an object. Let it use that assembler so
that we don't have to deal with assembly syntax incompatibilities.
