Benjamin Kramer 3a6afef4e7 Emit a better error when running out of registers on inline asm.
The most likely case where this error happens is when the user specifies
too many register operands. Don't make it look like an internal LLVM bug
when we can see that the error is coming from an inline asm instruction.
For other instructions we keep the "ran out of registers" error.
