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.
llvm-svn: 280672
This adds support for modules that require (non-)freestanding
environment, such as the compiler builtin mm_malloc submodule.

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.

Reapply r278457 with test fixed to not abouse fs case sensitivity.
When the VFS uses a YAML file, the real file path for a
virtual file is described in the "external-contents" field. Example:
...
{
'type': 'file',
'name': 'a.h',
'external-contents': '/a/b/c/a.h'
}
Currently, when parsing umbrella directories, we use
vfs::recursive_directory_iterator to gather the header files to generate the
equivalent modules for. If the external contents for a header does not exist,
we currently are unable to build a module, since the VFS
vfs::recursive_directory_iterator will fail when it finds an entry without a
reliable real path.
Since the YAML file could be prepared ahead of time and shared among
different compiler invocations, an entry might not yet have a reliable
path in 'external-contents', breaking the iteration.
Give the VFS the capability to skip such entries whenever
'ignore-non-existent-contents' property is set in the YAML file.

llvm-svn: 278457
Add 'ignore-non-existent-contents' to tell the VFS whether an invalid path
obtained via 'external-contents' should cause iteration on the VFS to stop.
If 'true', the VFS should ignore the entry and continue with the next. Allows
YAML files to be shared across multiple compiler invocations regardless of
prior existent paths in 'external-contents'. This global value is overridable
on a per-file basis.
This adds the parsing and write test part, but use by VFS comes next.

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

This patch is similar to the implementation of 'private' clause: it adds a list of private pointers to be used within the target data region to store the device pointers returned by the runtime.
Please refer to the following document for a full description of what the runtime witll return in this case (page 10 and 11):

I am happy to answer any question related to the runtime interface to help reviewing this patch.

Some compilers are too dumb to realize that the switch statement covers
all cases.
(Don't use a "default" label, because we explicitly want to get a warning
if our switch doesn't cover all the cases.)

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.
