Unfortunately that doesn't say much since it's the only one that your
CPU supports.
Can someone with a SSE2 CPU test if disabling all others so that the
ff_imdct36_float_sse will be used breaks for them, too?
I looked at the SSE-only code a bit but could not see anything that
would break SSE compared to e.g. SSE2...
