Tweak *mmintrin.h so that they don't make any bad assumptions about alignment (which probably has little effect in practice, but better to get it right). Make the load in _mm_loadh_pi and _mm_loadl_pi a single LLVM IR instruction to make optimizing easier for CodeGen.

Switch clang over to using fence/atomicrmw/cmpxchg instead of the intrinsics (which will go away). LLVM CodeGen does almost exactly the same thing with these and the old intrinsics, so I'm reasonably confident this will not break anything.
...
There are still a few issues which need to be resolved with code generation for atomic load and store, so I'm not converting the places which need those for now.
I'm not entirely sure what to do about __builtin_llvm_memory_barrier: the fence instruction doesn't expose all the possibilities which can be expressed by __builtin_llvm_memory_barrier. I would appreciate hearing from anyone who is using this intrinsic.

Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.
...
A homogeneous aggregate is an aggregate data structure where after flattening
any nesting there are 1 to 4 elements of the same base type that is either a
float, double, or Neon vector. All Neon vectors of the same size, either 64
or 128 bits, are treated as equivalent for this purpose. When using the
AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by
expanding them into a sequence of their base types. This requires extending
the existing support for expanded arguments to handle not only structs, but
also constant arrays and complex types.

Enhance the IR type lowering code to be much smarter about recursively lowering
...
types. Fore xample, we used to lower:
struct bar { int a; };
struct foo {
void (*FP)(struct bar);
} G;
to:
%struct.foo = type { {}* }
since the function pointer would cause recursive translation of bar and
we didn't know if that would get us into trouble. We are now smart enough
to know that it is fine, so we get this type instead:
%struct.foo = type { void (i32)* }
Codegen still needs to be prepared for uncooperative types at any place,
which is why I let the maximally uncooperative code sit around for awhile to
help shake out the bugs.

stuff like this:
typedef struct {

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.

When emitting a compound literal of POD type, continue to emit a
...
separate aggregate temporary and then memcpy it over to the
destination. This fixes a regression I introduced with r133235, where
the compound literal on the RHS of an assignment makes use of the
structure on the LHS of the assignment.
I'm deeply suspicious of AggExprEmitter::VisitBinAssign()'s
optimization where it emits the RHS of an aggregate assignment
directly into the LHS lvalue without checking whether there is any
aliasing between the LHS/RHS. However, I'm not in a position to
revisit this now.
Big thanks to Eli for finding the regression!

The LLVM IR representation of byval arguments has a rather strange property: if the alignment of an argument to a call is less than the specified byval alignment for that argument, there is no way to specify the alignment of the implied copy. Therefore, we must ensure that the alignment of the argument is at least the byval alignment. To do this, we have to mess with the alignment of relevant alloca's in some cases, and insert a copy that conceptually shouldn't be necessary in some cases.
...
This patch tries relatively hard to avoid creating an extra copy if it can be avoided (see test3 in the included testcase), but it is not possible to avoid in some cases (like test2 in the included testcase).

Fix a miscompilation I introduced in r129652, thanks for Eli for tracking
...
it down. we effectively were compile the testcase into:
void test14(int x) {
switch (x) {
case 11: break;
case 42: test14(97); // fallthrough
default: test14(42); break;
which is not the same thing at all. This fixes a miscompilation of
MallocBench/gs seen on the clang-x86_64-linux-fnt buildbot.
