When a block within a function accesses a function's static local variable,
this local is captured by reference rather than copied to the heap.

Therefore this variable's memory space is known: StaticGlobalSpaceRegion.
Used to be UnknownSpaceRegion, same as for stack locals.

Fixes a false positive in MacOSXAPIChecker.

The DSAChecker code in SemaOpenMP looks at the captured statement
associated with an OpenMP directive.  A combined directive such as
'target parallel' has nested capture statements, which have to be
fully traversed before executing the DSAChecker.  This is a patch
to perform the traversal for such combined directives.

where the vtable is emitted - reducing redundant debug info) ensure the
debug info class definition is still omitted when an
available_externally vtable definition is emitted for optimization
purposes.

Summary:
Specifically, we upgrade llvm.nvvm.:

 * brev{32,64}
 * clz.{i,ll}
 * popc.{i,ll}
 * abs.{i,ll}
 * {min,max}.{i,ll,u,ull}
 * h2f

These either map directly to an existing LLVM target-generic
intrinsic or map to a simple LLVM target-generic idiom.

In all cases, we check that the code we generate is lowered to PTX as we
expect.

These builtins don't need to be backfilled in clang: They're not
accessible to user code from nvcc.

For a << b (as original vec_sl does), if b >= sizeof(a) * 8, the
behavior is undefined. However, Power instructions do define the
behavior, which is equivalent to a << (b % (sizeof(a) * 8)).

This patch changes altivec.h to use a << (b % (sizeof(a) * 8)), to
ensure the consistent semantic of the instructions. Then it combines
the generated multiple instructions back to a single shift.

This patch handles left shift only. Right shift, on the other hand, is
more complicated, considering arithematic/logical right shift.

Summary:
rL292562 added a fix to always format if the fallback style is set to "none".
In test/Format/style-on-command-line.cpp:19 is redundant, since -fallback-style
has a default value of LLVM set in ClangFormat.cpp:72.

@amaiorano: I believe that the rest of the test cases still cover your change in
case the fallback style is explicitly set to "none". Please, if this is not the
case, initiate a discussion.

Summary: Instead of picking the buffer file coding system, always use utf-8-unix for communicating with clang-format.  This is fine because clang-format never actually reads the file to be formatted, only standard input.  This is a bit simpler (process coding system is now a constant) and potentially faster, as utf-8-unix is Emacs's internal coding system.  Also add an end-to-end test that actually invokes clang-format.
