* tc-mips.c (mips_cprestore_valid): New flag.
        (mips_frame_reg_valid): New flag.
        (macro) [M_JAL_2]: Check both flags.
        [M_JAL_A]: Likewise.
        (s_cprestore): Set mips_cprestore_valid.
        (tc_get_register): If setting mips_frame_reg, set
        mips_frame_reg_valid and clear mips_cprestore_valid.
        (s_mips_ent): Clear both flags.
        (s_mips_end): Clear both flags.
