Without SSE2, we don't combine the separate loads in foo2 and get
separate rotates, instead of a bswap.
Regstrapped on x86_64-linux-gnu. Also tested with gcc-14 on aarch64-,
arm-, x86-, and x86_64-vxworks7r2. Ok to install?
for gcc/testsuite/ChangeLog
* gcc.target/i386/pr108938-3.c: Add -msse2.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
