Turn on the new instprinter by default.
Turn on the new instprinter by default.

The only change in the output is:

1) we get a better comment on mfcr, we get:
	mfcr r2                         ; cr2
  instead of:
 	mfcr r2 ; 32

2) we no longer emit $stub's on powerpc/leopard.  The Leopard
   linker autosynthesizes them.
