i386: Fix mmx.md signbit expanders [PR112816]
Apparently when looking for "signbit<mode>2" vector expanders, I've only looked at sse.md and forgot mmx.md, which has two further ones and the following patch still ICEd. 2023-12-19 Jakub Jelinek <jakub@redhat.com> PR target/112816 * config/i386/mmx.md (signbitv2sf2, signbit<mode>2): Force operands[1] into a REG. * gcc.target/i386/sse2-pr112816-2.c: New test.
