When performing layout for an Objective-C class, make sure to dig out
the definition of that class. Fixes PR11613 / <rdar://problem/10604077>.

Add AVX2 intrinsics for pavg, pblend, and pcmp instructions. Also remove unneeded builtins for SSE pcmp. Change SSE pcmpeqq and pcmpgtq to not use builtins and just use vector == and >.

Update the CMake build for r146959's new files.

Relax type checking for a few Neon intrinsics. <rdar://problem/10538555>

Not long ago, I tightened up the type checking for pointer arguments of
Neon intrinsics to match the specifications provided by ARM. One consequence
was that it became impossible to access the unaligned versions of a few
Neon load/store operations. Since there are just a few of these intrinsics
where it makes a difference, I think it's better to relax the type checking
than to either introduce new non-standard unaligned intrinsics or to disallow
intrinsics for the unaligned operations.

Fix off-by-one error in an assert condition. No functionality change, but better
error detection.

Revert r146766, and add a testcase for which it introduced a wrong-code bug.

Commit by rsmith :: r146955 /cfe/trunk/ (11 files in 6 dirs): (link)

Unlike in C++03, a constant-expression is not an unevaluated operand in C++11.
Split out a new ExpressionEvaluationContext flag for this case, and don't treat
it as unevaluated in C++11. This fixes some crash-on-invalids where we would
allow references to class members in potentially-evaluated constant expressions
in static member functions, and also fixes half of PR10177.

The fix to PR10177 exposed a case where template instantiation failed to provide
a source location for a diagnostic, so TreeTransform has been tweaked to supply
source locations when transforming a type. The source location is still not very
good, but MarkDeclarationsReferencedInType would need to operate on a TypeLoc to
improve it further.

Also fix MarkDeclarationReferenced in C++98 mode to trigger instantiation for
static data members of class templates which are used in constant expressions.
This fixes a link-time problem, but we still incorrectly treat the member as
non-constant. The rest of the fix for that issue is blocked on PCH support for
early-instantiated static data members, which will be added in a subsequent
patch.

Fix tentative parsing so it knows how to handle an ambiguous for-range-declaration. PR11601.

Remove some extraneous carriage returns from these files. One of the
Windows subversion clients isn't setup to default to eol:native again...

Refine error diagnostic for using bridged casts when not using ARC.

Commit by dgregor :: r146933 /cfe/trunk/ (9 files in 6 dirs): (link)

Detect when mapping a #include/#import over to a submodule ends up
hitting a submodule that was never actually created, e.g., because
that header wasn't parsed. In such cases, complain (because the
module's umbrella headers don't cover everything) and fall back to
including the header.

Later, we'll add a warning at module-build time to catch all such
cases. However, this fallback is important to eliminate assertions in
the ASTWriter when this happens.

Evaluation support for ExprWithCleanups. We won't evaluate any expression which
actually requires non-trivial cleanups, so no cleanups need to be performed.
