I put a few peephole optimizations in our assembler.  It was mostly
because we had

   n:    blah blah   (N+1)
   n+1   flip 1   target target

Because the source language for the compiler was easier to write if some
branches were separate instructions.  The optimizer would combine the
target into the 'n' instruction, and eliminate the flip instruction.
