Sema actions on ObjCDictionaryLiteral and ObjCArryLiteral are currently
done as a side-effect of Sema upon parent expressions, which incurs of
delayed typo corrections for such literals to be performed by TypoTransforms
upon the ObjCDictionaryLiteral and ObjCArryLiteral themselves instead of
its elements individually.
This is specially bad because it was not designed to act on several
elements; searching through all possible combinations of corrections for
several elements is very expensive. Additionally, when one of the
elements has no correction candidate, we still explore all options and
at the end emit no typo corrections whatsoever.
Do the proper sema actions by acting on each element alone during appropriate
literal parsing time to get proper diagonistics and decent compile time
behavior.

Added the opencl.ocl.version metadata to be emitted with amdgcn. Created a static function emitOCLVerMD which is shared between triple spir and target amdgcn.
Also added new testcases to existing test file, spir_version.cl inside test/CodeGenOpenCL.

It's a patch for PR28050. Seems like overloading resolution wipes out

in case of deprecated string literal conversion.

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
-fno-integrated-as.

Compute an effective target triple exactly once in ConstructJob(), and
then simply pass around references to it. This eliminates wasteful

No in-tree targets access this `DefaultTargetTriple` directly, and usage
of default triples is generally discouraged. Make the field private.
This is part of en effort to make the clang driver use effective triples

For assembly files without .intel_syntax or .att_syntax directives, allow the
-masm= flag to supply a default assembly dialect. For example,
C:\TMP> type intel.s
.text
mov al,0
C:\TMP> clang -masm=intel -c intel.s
Without this patch, one would need to pass an "-mllvm -x86-asm-syntax=" flag
directly to the backend.
C:\TMP> clang -mllvm --x86-asm-syntax=intel -c intel.s

This checker checks copy and move assignment operators whether they are
protected against self-assignment. Since C++ core guidelines discourages
explicit checking for `&rhs==this` in general we take a different approach: in
top-frame analysis we branch the exploded graph for two cases, where &rhs==this
and &rhs!=this and let existing checkers (e.g. unix.Malloc) do the rest of the
work. It is important that we check all copy and move assignment operator in top
frame even if we checked them already since self-assignments may happen
undetected even in the same translation unit (e.g. using random indices for an
array what may or may not be the same).

No functional change, just some cleanups:
- Use auto when it is appropriate.

This patch adds a new AST node: ObjCAvailabilityCheckExpr, and teaches the
Parser and Sema to generate it. This node represents an availability check of
the form:
@available(macos 10.10, *);
Which will eventually compile to a runtime check of the host's OS version. This
is the first patch of the feature I proposed here:

Summary:
This patch replaces the CUDA specific action by a generic offload action. The offload action may have multiple dependences classier in “host” and “device”. The way this generic offloading action is used is very similar to what is done today by the CUDA implementation: it is used to set a specific toolchain and architecture to its dependences during the generation of jobs.
This patch also proposes propagating the offloading information through the action graph so that that information can be easily retrieved at any time during the generation of commands. This allows e.g. the "clang tool” to evaluate whether CUDA should be supported for the device or host and ptas to easily retrieve the target architecture.
This is an example of how the action graphs would look like (compilation of a single CUDA file with two GPU architectures)
