Bill Wendling 48939ced20 Update testcases due to Attribute sorting improvements.

Bill Wendling 85ab57ac5d Update the tests. 
This update coincides with r174110. That change ordered the attributes
alphabetically.

Bill Wendling 9806806f39 Modify the tests for the (sorted) order that the attributes come out as now.

Eli Friedman a92db6773a Fix a small calling-convention bug for x86-32. PR14453.

Eli Friedman 0b3f201b61 Fix the meaning of an "empty" record for the case of a zero-length array. Use isEmptyRecord for arguments on x86-32; there are structs of size 0 which don't count as empty.

Eli Friedman 1d7dd3b682 A bunch of fixes to argument passing and va_arg on Darwin x86-32 for structures containing an SSE vector.

Eli Friedman ee94534662 Simplify code for returning a struct for Darwin x86-32 ABI. Use a better type for a function returning a struct containing only a pointer. Handle the edge case of a struct containing only a float or double plus some dead padding instead of asserting.

John McCall a5efa7386a Track whether an AggValueSlot is potentially aliased, and do not 
emit call results into potentially aliased slots.  This allows us
to properly mark indirect return slots as noalias, at the cost
of requiring an extra memcpy when assigning an aggregate call
result into a l-value.  It also brings us into compliance with
the x86-64 ABI.

Chris Lattner a5f58b05e8 clang side to match the LLVM IR type system rewrite patch.

Eli Friedman 3346582bca Change -mno-mmx to be more compatible with gcc. Specifically, -mno-mmx should not imply -mno-sse. 
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.

Chris Lattner e76b95ae15 make the x86-32 backend specify a byval alignment, even when the 
code generator will do it.  With this patch, clang compiles the example
in PR9794 to not have an alloca temporary.

Daniel Dunbar dd38fbc7fb IRgen/ABI/x86-32: Realign indirect arguments when the ABI requires us to pass 
them with a smaller alignment than the rest of codegen expects.

Daniel Dunbar ed23de3348 IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types get passed 
with a non-default-stack-ABI-alignment (of 16).
 - This fixes the ABI convenient, but breaks codegen since we now have
   underaligned arguments. Marginal improvement overall though, and will be
   fixed in next commit.
