    match.pd: When simplifying BFR of an insert, require a mode precision
integral type [PR108688]

    The same problem as PR 88739 has crept in but
    this time in match.pd when simplifying bit_field_ref of
    an bit_insert. That is we are generating a BIT_FIELD_REF
    of a non-mode-precision integral type.

            PR tree-optimization/108688
            * match.pd (bit_field_ref [bit_insert]): Avoid generating
            BIT_FIELD_REFs of non-mode-precision integral operands.

            * gcc.c-torture/compile/pr108688-1.c: New test.
