Summary:
This fixes a bug where we were unable to compile the following CUDA
file with libstdc++ (didn't try libc++):
#include <future>
void foo() { std::shared_future<int> x; }
The problem is that <future> only defines std::shared_future if
__GCC_ATOMIC_INT_LOCK_FREE > 1. When we compiled this file for device,
the macro was set to 1, and then the class didn't exist at all.

OpenCL requires __ENDIAN_LITTLE__ be set for little endian targets.
The default for targets was also apparently big endian, so AMDGPU
was incorrectly reported as big endian. Set this from the triple
so targets don't have another place to set the endianness.

I'm in the progress of adding ARMv6 support to CloudABI. On the compiler
side, everything seems to work properly with this tiny change applied.

Summary:
We want wasm and asmjs to have matching ABIs, and right now asmjs uses
unsigned int for its size_t. This causes exported symbols in libcxx to
not match and can cause weird breakage where libcxx doesn't get linked
as a result. Long-term we probably want wasm32, wasm64, and asmjs to
all use unsigned long, but that would cause unnecessary ABI churn for
asmjs so defer that until we can make all the ABI changes at once.

Pointers of certain GPUs in AMDGCN target in private address space is 32 bit but pointers in other address spaces are 64 bit. size_t type should be defined as 64 bit for these GPUs so that it could hold pointers in all address spaces. Also fixed issues in pointer arithmetic codegen by using pointer specific intptr type.

Adjust target features for amdgcn target when -cl-denorms-are-zero is set.
Denormal support is controlled by feature strings fp32-denormals fp64-denormals in amdgcn target. If -cl-denorms-are-zero is not set and the command line does not set fp32/64-denormals feature string, +fp32-denormals +fp64-denormals will be on for GPU's supporting them.
A new virtual function virtual void TargetInfo::adjustTargetOptions(const CodeGenOptions &CGOpts, TargetOptions &TargetOpts) const is introduced to allow adjusting target option by codegen option.

The size of image type is reported incorrectly as size of a pointer to address space 0, which causes error when casting image type to pointers by __builtin_astype.
The fix is to get image address space from TargetInfo then report the size accordingly.

Summary:
In RenderScript, the size of the argument or return value emitted in the
IR is expected to be the same as the size of corresponding qualified
type. For ARM and AArch64, the coercion performed by Clang can
change the parameter or return value to a type whose size is different
(usually larger) than the original aggregate type. Specifically, this
can happen in the following cases:
- Aggregate parameters of size <= 64 bytes and return values smaller
than 4 bytes on ARM
- Aggregate parameters and return values smaller than bytes on
AArch64
This patch coerces the cases above to an integer array that is the same
size and alignment as the original aggregate. A new field is added to
TargetInfo to detect a RenderScript target and limit this coercion just
to that case.
Tests added to test/CodeGen/renderscript.c

Summary:
N32 and N64 follow the standard ELF conventions (.L) whereas O32 uses its own

This fixes the majority of object differences between -fintegrated-as and

Summary:
Currently our handling of CUDA architectures is scattered all around
clang. This patch centralizes it.
A key advantage of this centralization is that you can now write a C++
switch on e.g. CudaArch and get a compile error if you don't handle one
of the enum values.

Summary:
The TargetInfo for 'renderscript32' and 'renderscript64' ArchTypes are
subclasses of ARMleTargetInfo and AArch64leTargetInfo respectively.
RenderScript32TargetInfo modifies the ARM ABI to set LongWidth and
LongAlign to be 64-bits. Other than this modification, the underlying
TargetInfo base classes is initialized as if they have "armv7" and
"aarch64" architecture type respectively.

We continue accepting "macosx" but canonicalize it to "macos", When emitting
diagnostics, we use "macOS" instead of "OS X".
The PlatformName in TargetInfo is changed from "macosx" to "macos" so we can
directly compare the Platform in AvailabilityAttr with the PlatformName
in TargetInfo.

Recently, Microsoft added support for a flag, /std, which controls which
version of the language rules MSVC should use.
MSVC hasn't updated __cplusplus though.
Instead, they added a new macro, _MSVC_LANG, which is defined in a
similar fashion to __cplusplus. This is used to indicate which mode the
compiler is in.

Summary:
The validity of ABI/CPU pairs is no longer checked on the fly but is
instead checked after initialization. As a result, invalid CPU/ABI pairs
can be reported as being known but invalid instead of being unknown. For
example, we now emit:
error: ABI 'n32' is not supported on CPU 'mips32r2'
instead of:
error: unknown target ABI 'n64'
