David Majnemer 0dcea0929b CodeGen: Simplify consecutive '%' modifiers 
LLVM the consecutive '%' modifiers are redundant, skip them.

Eric Christopher c5f9a011a5 Add support for AVX registers to clang inline asm. Add a small testcase 
and update the Sema testcase with a register that we won't hit for a while
I hope.

Chris Lattner aab64d0b7f Implement PR6845. We allow matching constraints to have different 
input and output types when the smaller value isn't mentioned in the
asm string.  Extend this support from integers to also allowing 
fp values to be mismatched (if not mentioned in the asm string).

Daniel Dunbar a5728872c7 Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
