If using -mwarn-cell-microcode, rs6000_final_prescan_insn calls
get_insn_template to get the name of the machine instruction. But,
get_insn_template calls the output template if that is code, and that
then can modify recog_data (it is normal to change the operands, for
example).
This patch saves and restores recog_data around the call to
get_insn_template to fix the problems this causes.
