fix PR 111259 invalid zcmp mov predicate.
The code changes are from Palmer.
root cause:
In a gcc build with --enable-checking=yes, REGNO (op) checks
rtx code and expected code 'reg'. so a rtx with 'subreg' causes
an internal compiler error.
solution:
Restrict predicate to allow 'reg' only.
gcc/ChangeLog:
* config/riscv/predicates.md: Restrict predicate
to allow 'reg' only.
