    * lra-eliminations.c (lra_eliminate_regs_1): Add new assert.
    Don't use difference of offset and previous offset if
    update_sp_offset is non-zero.
    (eliminate_regs_in_insn): Ditto.
    * lra-spills.c (remove_pseudos): Exchange 4th and 6th args in
    lra_eliminate_regs_1 call.
    * lra-constraints.c (get_equiv_with_elimination): Ditto.
