Is there any way to still access MMX instructions/registers with intrinsics in
gcc-10 at all or is this bug "fixable but that code generation option will go
away entirely with gcc-10 so it wouldn't matter" then?

The generated code is created the way it is partially by design, and partially
by missing (!y,*x) alternative in *vec_extractv2di_0_sse. GCC lowers intrinsics
to generic operations, and this has its pluses
