    mips: check MSA support for vector modes [PR100760,PR100761,PR100762]

    Check if the vector mode is really supported by MSA in certain cases,
    instead of testing ISA_HAS_MSA.  Simply testing ISA_HAS_MSA can cause
    ICE when MSA is enabled besides other MIPS SIMD extensions (notably,
    Loongson MMI).

            * config/mips/mips.c (mips_const_insns): Use MSA_SUPPORTED_MODE_P
            instead of ISA_HAS_MSA.
            (mips_expand_vec_unpack): Likewise.
            (mips_expand_vector_init): Likewise.
