Richard Sandiford - May 28, 2011, 7:41 a.m.
I'd got confused when doing the genrecog position thing, and converted
the match_op_dup '0'-based positions into XVECEXP0 rather than XEXP.

The patch below restores powerpc64's insn-recog.c to the form it had
before the changes.  Applied as obvious.

Sorry for the breakage.
