[ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a
...
CodeGen option to a LangOpt option. In turn, hoist the guard into the parser
so that we avoid the new (and fairly unstable) Sema/AST/CodeGen logic. This
should restore the behavior of clang to that prior to r158325.

When performing a trivial copy of a C++ type, we must be careful not

to overwrite objects that might have been allocated into the type's

correctness.

Fix a pair of bugs relating to properties in ARC.
...
First, when synthesizing an explicitly strong/retain/copy property
of Class type, don't pretend during compatibility checking that the
property is actually assign. Instead, resolve incompatibilities
by secretly changing the type of *implicitly* __unsafe_unretained
Class ivars to be strong. This is moderately evil but better than
what we were doing.
Second, when synthesizing the setter for a strong property of
non-retainable type, be sure to use objc_setProperty. This is
possible when the property is decorated with the NSObject
attribute. This is an ugly, ugly corner of the language, and
we probably ought to deprecate it.
The first is rdar://problem/12039404; the second was noticed by
inspection while fixing the first.

Avoid using i64 types for vld1q_lane/vst1q_lane intrinsics.
...
The backend has to legalize i64 types by splitting them into two 32-bit pieces,
which leads to poor quality code. If we produce code for these intrinsics that
uses one-element vector types, which can live in Neon vector registers without
getting split up, then the generated code is much better. Radar 11998303.
