add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers.  Patch originally by ARM;
language-specific address space support by myself.

 - We don't really support the majority of the horrible -traditional-cpp
   behavior, but it is unlikely that we ever will either. This allows us to
   start trying to use clang as a /usr/bin/cpp replacement and see what pieces
   of -traditional-cpp mode people actually care about.

Use the newly added FileManager::getNoncachedStatValue when trying to determine if any files in the preamble have changed.

llvm-svn: 127894

Add FileManager::getNoncachedStatValue, which will resolve relative paths against the working directory specified in the file system options.

Construct 'Sema' object on the stack, so that crash recovery can recovery it's associated resources without walking over dead stack space.

llvm-svn: 127864

Issue this as an IR-gen error;  it's not really worthwhile doing this
"right", i.e. in Sema, because IR gen knows a lot of tricks beyond
what the constant evaluator knows.

Use CrashRecoveryContextCleanup objects to recover an ASTUnit if we crash in ASTUnit::LoadFromCommandLine() and ASTUnit::LoadFromCompilerInvocation().

Use CrashRecoveryContextCleanup objects to release resources associated with Sema during a crash while parsing.

Fix PR9488: 'auto' type substitution can fail (for instance, if it creates a reference-to-void type). Don't crash if it does.
Also fix an issue where type source information for the resulting type was being lost.

Remove code that was intentionally generating bad code on the GNU runtime for no reason (failing to emit .cxx_constructor / .cxx_destructor methods).

llvm-svn: 127806

Don't construct two CFGs just to run -Wuninitialized.  While this causes new warnings to be flagged under -Wconditional-uninitialized, this is something we
can improve over time.

Teach VariadicMethodTypeChecker that CF references are valid arguments to variadic Objective-C methods.

Tweak RegionStore's handling of lazy compound values to use the 'Default' versus 'Direct' binding key, thus allowing specific elements of an array/struct to be overwritten without
invalidating the entire binding.  Fixes PR 9455.
