i386: Make flags_reg_operand a special predicate
There is no need to check the mode in flags_reg_operand predicate. The
mode in flags setting instructions is checked with ix86_match_ccmode.
The patch avoids "warning: operand X missing mode?" warnings with
VOIDmode flags_reg_operand predicate.
gcc/ChangeLog:
* config/i386/predicates.md ("flags_reg_operand"):
Make predicate special to avoid automatic mode checks.
