The issue can't be reproduced on current trunk.

Right it seems like it was fixed in GCC 10.1.0. I have not looked into why
though.

According to my git bisect, this was fixed for gcc-10.1.0 by
d4410ec0ab4e3d2c834a811acf9e39af32e1d1d8 is the first new commit
commit d4410ec0ab4e3d2c834a811acf9e39af32e1d1d8
Author: H.J. Lu <hongjiu.lu@intel.com>

i386: Allow MMX vector expanders with TARGET_MMX_WITH_SSE
PR target/89021
...
From-SVN: r271251
but it's part of a long series of patches (see PR89021) and I doubt it's
backportable as-is.
