PR debug/66691
* lra-int.h (lra_substitute_pseudo): Add a parameter.
(lra_substitute_pseudo_within_insn): Ditto.
* lra.c (lra_substitute_pseudo): Add a parameter. Simplify subreg
of constant.
(lra_substitute_pseudo_within_insn): Add a parameter. Transfer it
to lra_substitute_pseudo.
* lra-lives.c (process_bb_lives): Add an argument to
lra_substitute_pseudo_within_insn call.
* lra-constraints.c (inherit_reload_reg, split_reg): Add an
argument to lra_substitute_pseudo and
lra_substitute_pseudo_within_insn calls.
(remove_inheritance_pseudos, undo_optional_reloads): Ditto.
