Eli Friedman 45966b4671 Remove the -arch option from clang-cc: for all practical purposes, it's 
redundant with -triple.

Chris Lattner cb66c73a48 If we have mismatched integer tied operands, but the operand 
number is not mentioned in the asm string, let it past sema. 
Right now these are currently rejected by the llvm code generator
but this will be fixed next.

Chris Lattner 574428e4db implement PR4077: [Linux kernel] inscrutable error on inline asm input/output constraint mismatch 
Before we emitted:

$ clang t.c -S -m64 
llvm: error: Unsupported asm: input constraint with a matching output constraint of incompatible type!

Now we produce:
$ clang t.c -S -m64 
t.c:5:40: error: unsupported inline asm: input with type 'unsigned long' matching output with type 'int'
  asm volatile("foo " : "=a" (a) :"0" (b));
                             ~~~      ~^~

Tests and drivers updated, still need to shuffle dirs.

Anders Carlsson 570c357ded If an input constraint refers to an output constraint, it should have the same constraint info as the output constraint. Fixes PR3417
