* regcprop.c (copyprop_hardreg_forward_1): Check may_trap_p on SET,
not INSN. Also check RTX_FRAME_RELATED_P. Queue insns for DF rescan
as needed.
(pass_cprop_hardreg::execute): Add df note problem and defer insn
rescans. Reprocess blocks as needed, calling df_analyze before
reprocessing. Always call df_analyze before fixing up debug bind
insns.
