    [Committed] PR target/110787: Revert QImode offsets in {zero,sign}_extract.

    My recent patch to use QImode for bit offsets in ZERO_EXTRACTs and
    SIGN_EXTRACTs in the i386 backend shouldn't have resulted in any change
    behaviour, but as reported by Rainer it produces a bootstrap failure in
    gm2.  This reverts the problematic patch whilst we investigate the
    underlying cause.

    Committed as obvious.
