  - Emit default-initialization of arrays that were partially initialized
    with initializer lists with a loop, rather than emitting the default
    initializer N times;
  - support destroying VLAs of non-trivial type, although this is not
    yet exposed to users; and
  - support the partial destruction of arrays initialized with
    initializer lists when an initializer throws an exception.

Note that because we don't usually touch the MMX registers anyway, all -mno-mmx needs to do is tweak the x86-32 calling convention a little for vectors that look like MMX vectors, and prevent the definition of __MMX__.

clang doesn't actually stop the user from using MMX inline asm operands or MMX builtins in -mno-mmx mode; as a QOI issue, it would be nice to diagnose, but I doubt it really matters much.

argument expansion to use the macro argument source locations as well.
Add a few tests to exercise this. There is still a bit more work needed

instantiation and improve diagnostics which are stem from macro
arguments to trace the argument itself back through the layers of macro
expansion.

This requires some tricky handling of the source locations, as the
argument appears to be expanded in the opposite direction from the
surrounding macro. This patch provides helper routines that encapsulate
the logic and explain the reasoning behind how we step through macros
during diagnostic printing.

This fixes the rest of the test cases originially in PR9279, and later
split out into PR10214 and PR10215.

There is still some more work we can do here to improve the macro
backtrace, but those will follow as separate patches.

where we have an immediate need of a retained value.

As an exception, don't do this when the call is made as the immediate
operand of a __bridge retain.  This is more in the way of a workaround
than an actual guarantee, so it's acceptable to be brittle here.

When a macro instantiation occurs, reserve a SLocEntry chunk with length the
full length of the macro definition source. Set the spelling location of this chunk
to point to the start of the macro definition and any tokens that are lexed directly
from the macro definition will get a location from this chunk with the appropriate offset.

For any tokens that come from argument expansion, '##' paste operator, etc. have their
instantiation location point at the appropriate place in the instantiated macro definition
(the argument identifier and the '##' token respectively).
This improves macro instantiation diagnostics:

Before:

t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int')
int y = M(/);
        ^~~~
t.c:5:11: note: instantiated from:
int y = M(/);
          ^

After:

t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int')
int y = M(/);
        ^~~~
t.c:3:20: note: instantiated from:
\#define M(op) (foo op 3);
                ~~~ ^  ~
t.c:5:11: note: instantiated from:
int y = M(/);
          ^

The memory savings for a candidate boost library that abuses the preprocessor are:

- 32% less SLocEntries (37M -> 25M)
- 30% reduction in PCH file size (900M -> 635M)
- 50% reduction in memory usage for the SLocEntry table (1.6G -> 800M)

Do not violate the opencl casting rules. This test case still illustrates the problem. In the future, we should throw an error when doing invalid casting.

throw-expressions, such that we don't consider the NRVO when the
non-volatile automatic object comes from outside the innermost try
scope (C++0x [class.copymove]p13). In C++98/03, our ASTs were
incorrect but it didn't matter because IR generation doesn't actually
apply the NRVO here. In C++0x, however, we were moving from an object
when in fact we should have copied from it. Fixes PR10142 /
