    i386: Fix *vec_extractv2sf_1 and *vec_extractv2sf_1 shufps alternative
[PR93828]

    shufps moves two of the four packed single-precision floating-point values
    from *destination* operand (first operand) into the low quadword of the
    destination operand.  Match source operand to the destination.

        PR target/93828
        * config/i386/mmx.md (*vec_extractv2sf_1): Match source operand
        to destination operand for shufps alternative.
        (*vec_extractv2si_1): Ditto.
