i386: Fix up signbit<mode>2 expander [PR112816]
The following testcase ICEs, because the signbit<mode>2 expander uses an
explicit SUBREG in the pattern around match_operand with register_operand
predicate. If we are unlucky enough that expansion tries to expand it
with some SUBREG as operands[1], we have two nested SUBREGs in the IL,
which is not valid and causes ICE later.
