rs6000: New insns setnbc and setnbcr
setnbc[r] is like setbc[r], but it writes -1 instead of 1 to the GPR.
2020-05-07 Segher Boessenkool <segher@kernel.crashing.org>
* config/rs6000/rs6000.md (*setnbc_<un>signed_<GPR:mode>): New
define_insn.
(*setnbcr_<un>signed_<GPR:mode>): New define_insn.
(*neg_eq_<mode>): Avoid for TARGET_FUTURE; add missing && 1.
(*neg_ne_<mode>): Likewise.
