David Majnemer ade4bee761 CodeGen: Let arrays be inputs to inline asm 
An array showing up in an inline assembly input is accepted in ICC and
GCC 4.8

This fixes PR20201.

Eric Christopher af6431077c 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.

Peter Collingbourne 05500ba6ec Fix assertion failure in CodeGen where the input operand to an asm 
instruction is tied to an output operand which is a pointer, and
the input operand is narrower than the output operand.

Chris Lattner db6d5cb892 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 8fbe78f6fc 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).

Added all the missing '&&'s that have crept in. :)

Chris Lattner f85a938985 Fix PR3682 by just disabling a broken assertion. This check should be 
done in sema, and is reflected by the existing PR3258.  In the meantime,
fix PR3682 by disabling a bogus assertion (which doesn't account for + 
operands).
