Turn a few more inline asm errors into "emitErrors" instead of fatal errors.

Before we'd get:

$ clang t.c 
fatal error: error in backend: Invalid operand for inline asm constraint 'i'!

Now we get:

$ clang t.c
t.c:16:5: error: invalid operand for inline asm constraint 'i'!
    "movq         (%4), %%mm0\n"
    ^

Which at least gets us the inline asm that is the problem.
