Correct failures with --enable-checking=yes,rtl.

        * config/microblaze/microblaze.c (microblaze_expand_shift):
        Replace GET_CODE test with CONST_INT_P and INTVAL test with
        test for const0_rtx.
        * config/microblaze/microblaze.md (ashlsi3_byone, ashrsi3_byone,
        lshrsi3_byone): Replace INTVAL with test for const1_rtx.
