You're right, though that surely was also a mistake.

I'm sure the native solaris compiler won't compile the
Intel __m64 datatype without mmx enabled, so it's not
like we could actually test to see if __m64 got returned
in integer registers.

Left as-is it means we'd change the ABI if we changed
ix86_vector_mode_supported_p to implement 64-bit vector
operations in the SSE unit.
