When replacing a LABEL_REF in a JUMP_INSN, add a REG_LABEL note. * reload.h (subst_reloads): Adjust prototype. * reload1.c (reload_as_needed): Pass INSN to subst_reloads. * jump.c (mark_all_labels): Canonicalize any REG_LABEL notes present in JUMP_INSNs and copy them to JUMP_LABEL. * flow.c (find_label_refs, find_basic_blocks_1): Skip JUMP_INSNs and insns with REG_LABELs that are followed by JUMP_INSNs with the same REG_LABEL. * sched-rgn.c (is_cfg_nonregular): Likewise. * rtlanal.c (computed_jump_p): Make it false if a REG_LABEL note is available. * unroll.c (unroll_loop): Look for REG_LABEL notes in JUMP_INSNs too. * rtl.texi (REG_LABEL): Document usage in JUMP_INSNs.
