    expmed: Use GET_MODE_PRECISION and expander's output mode.

    This changes the vec_extract path of extract_bit_field to use
    GET_MODE_PRECISION instead of GET_MODE_BITSIZE and uses
    the mode obtained from insn_data[icode].operand[0] as target mode.

    Also, it adds a vec_extract<mode>bi expander for riscv that maps
    to vec_extract<mode>qi.  This fixes an ICE on riscv where we did
    not find a vec_extract optab and continued with the generic code
    which requires 1-byte alignment that riscv mask modes do not provide.

    Apart from that it adds poly_int support to riscv's vec_extract
    expander and makes the RVV..BImode -> QImode expander call
    emit_vec_extract in order not to duplicate code.

    gcc/ChangeLog:

            PR target/112773

            * config/riscv/autovec.md (vec_extract<mode>bi): New expander
            calling vec_extract<mode>qi.
            * config/riscv/riscv-protos.h (riscv_legitimize_poly_move):
            Export.
            (emit_vec_extract): Change argument from poly_int64 to rtx.
            * config/riscv/riscv-v.cc (shuffle_extract_and_slide1up_patterns):
            Ditto.
            * config/riscv/riscv.cc (riscv_legitimize_poly_move): Export.
            (riscv_legitimize_move): Use rtx instead of poly_int64.
            * expmed.cc (store_bit_field_1): Change BITSIZE to PRECISION.
            (extract_bit_field_1): Change BITSIZE to PRECISION and use
            return mode from insn_data as target mode.
