invalid output constraint '+a' in asm

[nickdesaulniers]

working around #1224 , I observe:

Looks like some of the inline asm constraint handling code needs to be taught about the new M68k backend. cc @mshockwave

Managed to fix this in Clang with no problem. Nevertheless after fixing this I bumped into a bunch of "unrecognized inline asm syntax XYZ" problems screaming from the assembler - namely m68k's MC part since m68k is using integrated assembler now (or just temporarily switching back to GNU AS by giving -fno-integrated-as to Clang if you want to bypass any assembly related issues).

I will close this issue with a pointer to the patch in the M68k-llvm's repo. And might file another issue regarding unrecognized inline asm syntax, if that's the best way to keep record
