Move builtins from the x86 specific scope into the global
scope. Their use is still limited to x86_64 and aarch64 though.
This allows wine on aarch64 to properly handle variadic functions.

This patch extends the -fzvector language feature to enable the new
"vector float" data type when compiling at -march=z14. This matches
the updated extension definition implemented by other compilers for
the platform, which is indicated to applications by pre-defining
__VEC__ to 10302 (instead of 10301).

This patch series adds support for the IBM z14 processor. This part includes:
- Basic support for the new processor and its features.
- Support for low-level builtins mapped to new LLVM intrinsics.
Support for the -fzvector extension to vector float and the new
high-level vector intrinsics is provided by separate patches.

This probably doesn't change anything because the frotend doesn't do anything with this feature and the backend will infer from the cpu string. So this is just for consistency with other cpus that support movbe.

Certain targets (e.g. amdgcn) require global variable to stay in global or constant address
space. In C or C++ global variables are emitted in the default (generic) address space.
This patch introduces virtual functions TargetCodeGenInfo::getGlobalVarAddressSpace
and TargetInfo::getConstantAddressSpace to handle this in a general approach.
It only affects IR generated for amdgcn target.

This moves determination of the ISA revision from the CPU name to
one single place, removing a bunch of duplicated code. It also
makes the supported ISA revisions available as feature strings.

This is prep work to add MOVBE to all Atom CPUs. This instruction didn't come in to the Nehalem/Westmere/SandyBridge/etc. line until later so there's no natural place to overlap the Atom CPUs into that part of the switch.

This introduces helper functions that set target defines for different ARMV8-A
architecture kinds. It fixes an issue that the v8.1 define ARM_FEATURE_QRDMX
was not set for v8.2. These helper functions make things more “scalable” if we
want to add ARMv8.3 at some point, and a cleanup has been done to hold the
architecture kind in one variable (instead of one for each).

Ananas is a home-brew operating system, mainly for amd64 machines. After
using GCC for quite some time, it has switched to clang and never looked
back - yet, having to manually patch things is annoying, so it'd be much
nicer if this was in the official tree.

This reverts commit r305399.
This breaks a build in libcxx:
libcxx/src/system_error.cpp:90:16: error: assigning to 'int' from incompatible type 'char *'
if ((ret = ::strerror_r(ev, buffer, strerror_buff_size)) != 0) {

1 error generated.
Which makes sense according to:

The test in r304929 broke multiple buildbots as it expected mips target to

Add options to clang: -mmadd4 and -mno-madd4, use it to enable or disable

Summary:
The thumb-mode target feature is used to force Thumb or ARM code
generation on a per-function basis. Explicitly adding +thumb-mode to
functions for thumbxx triples enables mixed ARM/Thumb code generation in
places where compilation units with thumbxx and armxx triples are merged
together (e.g. the IR linker or LTO).
For armxx triples, -thumb-mode is added in a similar fashion.

The WebAssembly threads proposal has changed such that C++
implementations can now declare that atomics up to 64 bits are
"lock free" in C++'s terms.
llvm-svn: 304859
Summary:
This patch adds support for the target("arm") and target("thumb")
attributes, which can be used to force the compiler to generated ARM or
Thumb code for a function.
In LLVM, ARM or Thumb code generation can be controlled by the
thumb-mode target feature. But GCC already uses target("arm") and
target("thumb"), so we have to substitute "arm" with -thumb-mode and
"thumb" with +thumb-mode.

Rationale: OpenCL kernels are called via an explicit runtime API
with arguments set with clSetKernelArg(), not as normal sub-functions.
Return SPIR_KERNEL by default as the kernel calling convention to ensure
the fingerprint is fixed such way that each OpenCL argument gets one
matching argument in the produced kernel function argument list to enable
feasible implementation of clSetKernelArg() with aggregates etc. In case
we would use the default C calling conv here, clSetKernelArg() might
break depending on the target-specific conventions; different targets
might split structs passed as values to multiple function arguments etc.
