I think it's a worthwhile simplification, even though it has
a small impact on performance and code size.

Even better, I'd like to see the m68k backend switch to
a higher level description for outputing asm instructions rather
than cumbersome strings full of escapes and formatting codes.

IIRC, the avr backend was using a very clean solution.  With proper
inlining, performance shouldn't even be an issue.

Another random idea: maybe we could genericize the avr idea
so it could be used in all backends.  The actual wrappers could
even be generated out of the bfd machine descriotions.

Although I can't approve patches, I ack this one.
