    match.pd: Fix up r15-8025 simplification [PR119287]

    The following testcase ICEs since r15-8025.
    tree_nop_conversion_p doesn't imply TREE_TYPE (@0) is uselessly convertible
    to type, e.g. they could be INTEGER_TYPEs with the same precision but
    different TYPE_SIGN.

    The following patch just adds a convert so that it creates a valid IL
    even in those cases.

            * match.pd (((X >> C1) & C2) * (1 << C1) to X & (C2 << C1)): Use
            (convert @0) instead of @0 in the substitution.

            * gcc.dg/pr119287.c: New test.
