    RISC-V: Fix vec_duplicate[bimode] expander [PR119572].

    Since r15-9062-g70391e3958db79 we perform vector bitmask initialization
    via the vec_duplicate expander directly.  This triggered a latent bug in
    ours where we missed to mask out the single bit which resulted in an
    execution FAIL of pr119114.c

    The attached patch adds the 1-masking of the broadcast operand.

            PR target/119572

    gcc/ChangeLog:

            * config/riscv/autovec.md: Mask broadcast value.
