[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.
