Jakob Stoklund Olesen 33a1b416ac Don't run RAFast in the optimizing regalloc pipeline. 
The fast register allocator is not supposed to work in the optimizing
pipeline. It doesn't make sense to compute live intervals, run full copy
coalescing, and then run RAFast.

Fast register allocation in the optimizing pipeline is better done by
RABasic.

Jakob Stoklund Olesen 54f7c59c1a Better diagnostics when inline asm fails to allocate. 
asm.c:2:7: error: ran out of registers during register allocation
  asm(""::"r"(0), "r"(1), "r"(2), "r"(3), "r"(4), "r"(5), "r"(6), "r"(7), "r"(8), "r"(9));

Jakob Stoklund Olesen a5c889982a Emit a proper error message when register allocators run out of registers. 
This can't be just an assertion, users can always write impossible inline
assembly. Such an assembly statement should be included in the error message.
