    i386: Sync move_max/store_max with prefer-vector-width [PR112824]

    Currently move_max follows the tuning feature first, but ideally it
    should sync with prefer-vector-width when it is explicitly set to keep
    vector move and operation with same vector size.

    gcc/ChangeLog:

            PR target/112824
            * config/i386/i386-options.cc (ix86_option_override_internal):
            Sync ix86_move_max/ix86_store_max with prefer_vector_width when
            it is explicitly set.

    gcc/testsuite/ChangeLog:

            PR target/112824
            * gcc.target/i386/pieces-memset-45.c: Remove
            -mprefer-vector-width=3D256.
