* gcse.c (cprop_jump): Make use of REG_EQUAL notes on both
setcc and jump, if they exist. If substituted instruction
fails to validate, store current effort in a REG_EQUAL note.
(cprop_insn): Don't attempt further substitutions if the
current instruction has been deleted.
(local_cprop_pass): Likewise.
* jump.c (redirect_jump): Also update REG_EQUAL note, if
one is attached to the jump instruction.
(invert_jump): Delete REG_EQUAL note on jump, if one exists.
