Fix test fails on powerpc-darwin.
The current implementation of “speculation_barrier”
and “group_end_nop” insns emit hard-wired register
names which causes tests using them to fail on Darwin,
at least, which uses “rNN” instead of “NN”.
The patch makes the register names for these insns use
the operand output mechanism to substitute the
appropriate variant when needed.

Many of these patterns only worked in 32-bit mode, and some only worked
