The new test FAILs on i686-linux and even on x86_64-linux I think
it doesn't actually test what was reported, unless one performs testing
with -march= for some XOP enabled CPU or -mxop.

The following patch fixes that, tested on x86_64-linux with
make check-g++ RUNTESTFLAGS='--target_board=unix\{-m32,-m32/-mno-sse/-mno-mmx,-m64\} i386.exp=pr112904.C'

	PR target/112904
	* g++.target/i386/pr112904.C: Add dg-do compile, dg-options -mxop
	and for ia32 also dg-additional-options -mmmx.
