Best would be

 .machine push
 .machine power6
source that needs power6 insn
 .machine pop

You could also use ".machine any" in place of ".machine power6" above,
which would continue to use the default encoding for branches ("y" vs
"at" bits), and mfcr, if you happened to have such insns before the
pop.
