    [PR97701] LRA: Don't narrow class only for REG or MEM.

    Reload pseudos of ALL_REGS class did not narrow class from constraint
    in insn (set (pseudo) (lo_sum ...)) because lo_sum is considered an
    object (OBJECT_P) although the insn is not a classic move.  To permit
    narrowing we are starting to use MEM_P and REG_P instead of OBJECT_P.
