rs6000: Fix for and_operand oversight (PR68332, PR67677)
Calling rs6000_is_valid_and_mask on a reg instead of on a const_int is not a good idea, as PR68332 and PR67677 as well as testing with --enable-checking=yes,rtl show. Fix this. PR target/66217 PR target/67677 PR target/68332 * config/rs6000/predicates.md (and_operand): Check that the operand is a const_int before calling rs6000_is_valid_and_mask. From-SVN: r230811
