OpenCL C Spec v2.0 Section 6.13.11
- Made c11 _Atomic being accepted only for c11 compilations
- Implemented CL2.0 atomics by aliasing them to the corresponding c11 atomic types using implicit typedef
- Added diagnostics for atomics Khronos extension enabling

CloudABI also supports the arc4random() function. We can enable compiler
warnings for rand(), random() and *rand48() on this system as well.

CloudABI is a pure cross compilation target. This means that we should
not add /usr/include and /usr/local/include. Instead, headers are stored
in $sysroot/$triple/include.
The method of going back to the sysroot (by using "../../..") is also
used in this function for some of the other environments (e.g., MinGW).

CloudABI can be identified by the __CloudABI__ preprocessor definition. The
system uses ELF executables.
CloudABI uses Unicode 7.0.0 for the encoding of wchar_t. As Unicode 7.0.0 is
synchronized with ISO/IEC 10646:2012 (released on 2012-06-01),
__STDC_ISO_10646__ is defined as 201206L.

Using declarations which are aliases to struct types have their name
used as the struct type's name for linkage purposes. Otherwise, make
sure to give an anonymous struct defined inside a using declaration a
mangling number to disambiguate it from other anonymous structs in the
same context.
This fixes PR22809.

Because the catchable type has a reference to its name, mangle the
location to ensure that two catchable types with different locations are
distinct.

We do not implicitly create an OpenCLImageAccessAttr, so this change only affects out of tree users. There is no way to test this behavior specifically that I can see, since this only affects implicit creation of attributes.
Fixes PR22403.

We want to replace as much custom x86 shuffling via intrinsics
as possible because pushing the code down the generic shuffle
optimization path allows for better codegen and less complexity
in LLVM.
This is the sibling patch for the LLVM half of this change:

Using clang as a cross-compiler with the 'target' option could be confusing
for those inexperienced in the realm of cross compiling.
This patch would allow the use of all these four variants of the target option:
-target <triple>
--target <triple>
-target=<triple>
--target=<triple>

The task region is emmitted in several steps:
Emit a call to kmp_task_t *__kmpc_omp_task_alloc(ident_t *, kmp_int32 gtid, kmp_int32 flags, size_t sizeof_kmp_task_t, size_t sizeof_shareds, kmp_routine_entry_t *task_entry).
Here task_entry is a pointer to the function:
kmp_int32 .omp_task_entry.(kmp_int32 gtid, kmp_task_t *tt) {
TaskFunction(gtid, tt->part_id, tt->shareds);
return 0;
}
Copy a list of shared variables to field shareds of the resulting structure kmp_task_t returned by the previous call (if any).
Copy a pointer to destructions function to field destructions of the resulting structure kmp_task_t.
Emit a call to kmp_int32 __kmpc_omp_task(ident_t *, kmp_int32 gtid, kmp_task_t *new_task), where new_task is a resulting structure from previous items.

Patch adds proper generation of debug info for all OpenMP regions. Also, all OpenMP regions are generated in a termination scope, because standard does not allow to throw exceptions out of structured blocks, associated with the OpenMP regions

move the operator delete updating into a separate update record so we can cope
with updating another module's destructor's operator delete.

check that private headers are in a list matching the role. (We can't perform
the opposite checks for non-private headers because we infer those.)

This is a recommit of r231150, reverted in r231409. Turns out
that -fsanitize=shift-base check implementation only works if the
shift exponent is valid, otherwise it contains undefined behavior
itself.
Make sure we check that exponent is valid before we proceed to
check the base. Make sure that we actually report invalid values
of base or exponent if -fsanitize=shift-base or
-fsanitize=shift-exponent is specified, respectively.

When passing a type with large alignment byval, we were specifying the type's
alignment rather than the alignment that the backend is actually capable of
producing (ABIAlign).
This would be OK (if odd) assuming the backend dealt with it prooperly,
unfortunately it doesn't and trying to pass types with "byval align 16" can
cause it to set fp incorrectly and trash the stack during the prologue. I'll be
fixing that in a separate patch, but Clang should still be emitting IR that's
as close to its intent as possible.
