* loop-invariant.c (struct use): Strengthen field "insn" from rtx
to rtx_insn *.
(struct invariant): Likewise.
(hash_invariant_expr_1): Likewise for param "insn".
(invariant_expr_equal_p): Likewise for param "insn1", "insn2".
(find_exits): Likewise for local "insn".
(create_new_invariant): Likewise for param "insn".
(check_dependencies): Likewise.
(find_invariant_insn): Likewise.
(record_uses): Likewise.
(find_invariants_insn): Likewise.
(find_invariants_bb): Likewise for local "insn".
(get_pressure_class_and_nregs): Likewise for param "insn".
(calculate_loop_reg_pressure): Likewise for local "insn".
