rs6000: Fix for -mwarn-cell-microcode (PR43763)

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.


        PR target/43763
        * config/rs6000/rs6000.c (rs6000_final_prescan_insn): Save and
        restore recog_data (including the operand rtxes inside it) around
        the call to get_insn_template.
