    match: Use wi::to_wide instead of tree_to_uhwi in mul_hi/mul_lo [PR126958]

    Just a small compile time optimization because wi::to_wide should have
almost
    no overhead in this case when comparing against a constant and/or a
generated
    mask.

    Pushed as obvious after a bootstrap/test on x86_64-linux-gnu.

            PR tree-optimization/126958

    gcc/ChangeLog:

            * match.pd (mul_hi): Use wi::to_wide instead of
            tree_fits_uhwi_p/tree_to_uhwi.
            (mul_lo): Likewise.
