Only half of the intrinsics in this file is documented here. The patch for the other half will be sent out later.

See https://llvm.org/bugs/show_bug.cgi?id=26894 for details. This change
fixes the incorrect flags to Clang and the piping issue. It also disables
the FileCheck portion of the test, which is currently failing.

Summary:
For PseudoObjectExpr, the DeclMatcher need to search only all the semantics
but also need to search pass OpaqueValueExpr for all potential uses for the
Decl.

Since it's provided by the compiler. This allows a system module map
file to declare a module for it.
No test change for cstd.m, since stdatomic.h doesn't function without a
relatively complete stdint.h and stddef.h, which tests using this module
don't provide.

Includes new built-in, conversion of built-in to target-independent intrinsic
and update in the header file. Tests are also updated. There is a second part in
the backend for which I will post a separate code-review. BACKEND PART SHOULD BE
COMMITTED FIRST.

This is mostly a one-time autoconversion of tests that checked assembly after
"-Owhatever" compiles to only run "opt -mem2reg" and check the assembly. This
should make them much more stable to changes in LLVM so they won't break on
unrelated changes.
"opt -mem2reg" is a compromise designed to increase the readability of tests
that check dataflow, while minimizing dependency on LLVM. Hopefully mem2reg is
stable enough that no surpises will come along.
Should address http://llvm.org/PR26815.

Summary: In some cases it can be proved statically that multidimensional array section refer to contiguous storage and can therefore be allowed in a map clause. This patch adds support for those cases in SEMA.

Original patch by Stefan Bühler http://reviews.llvm.org/D12834
Difference between original and this one:
- fixed all comments in original code review
- added more tests, all new diagnostics now covered by tests
- moved abi_tag on re-declaration checks to Sema::mergeDeclAttributes
where they actually may work as designed
- clang-format + other stylistic changes
Mangle part will be sent for review as a separate patch.

OpenMP 4.5 allows privatization of non-static data members in OpenMP
constructs. Patch adds proper codegen support for data members in
'linear' clause
llvm-svn: 263003
This patch extends the -fuse-ld option to accept a full path to an executable
and use it verbatim to invoke the linker. There are generally two reasons
to desire this.
The first reason relates to the sad truth is that Clang is retargetable,
Binutils are not.
While any Clang from a binary distribution is sufficient to compile code
for a wide range of architectures and prefixed BFD linkers (e.g.
installed as /usr/bin/arm-none-linux-gnueabi-ld) as well as cross-compiled
libc's (for non-bare-metal targets) are widely available, including on all
Debian derivatives, it is impossible to use them together because
the -fuse-ld= option allows to specify neither a linker prefix nor
a full path to one.
The second reason is linker development, both when porting existing linkers
to new architectures and when working on a new linker such as LLD.

This is one of a series of changes to improve the MSVC visualization of Clang types.
This one focuses on Record and SubstTemplateTypeParmType meaning that, for example,
a TemplateArgumentLoc no longer displays incomprehensibly in the locals window as
{Argument={DeclArg={Kind=1 QT=0x033acb00 D=0xcccccccc {DeclType=???}}...
but instead much more usefully as
Type template parameter: SubstTemplateTypeParm: {Identifier (("T"))} => Record, {Identifier (("A"))}
Additional types and improvements will be made in subsequent commits

Similar to the template cases in r262050, when a C++ method in an
unavailable struct/class calls unavailable API, don't diagnose an error.
I.e., this case was failing:
void foo() __attribute__((unavailable));
struct __attribute__((unavailable)) A {
void bar() { foo(); }
};
Since A is unavailable, A::bar is allowed to call foo. However, we were
emitting a diagnostic here. This commit checks up the context chain
from A::bar, in a manner inspired by SemaDeclAttr.cpp:isDeclUnavailable.
I expected to find other related issues but failed to trigger them:
- I wondered if DeclBase::getAvailability should check for
`TemplateDecl` instead of `FunctionTemplateDecl`, but I couldn't find
a way to trigger this. I left behind a few extra tests to make sure
we don't regress.
- I wondered if Sema::isFunctionConsideredUnavailable should be
symmetric, checking up the context chain of the callee (this commit
only checks up the context chain of the caller). However, I couldn't
think of a testcase that didn't require first referencing the
unavailable type; this, we already diagnose.

This is a follow-up to r261512, which made the 'strict' availability
attribute flag behave like 'unavailable'. However, that fix was
insufficient. The following case would (erroneously) error when the
deployment target was older than 10.9:
struct __attribute__((availability(macosx,strict,introduced=10.9))) A;
__attribute__((availability(macosx,strict,introduced=10.9))) void f(A*);
The use of A* in the argument list for f is valid here, since f and A
have the same availability.
The fix is to return AR_Unavailable from DeclBase::getAvailability
instead of AR_NotYetIntroduced. This also reverts the special handling
added in r261163, instead relying on the well-tested logic for
AR_Unavailable.
