The problem is that MUST_PASS_IN_MEMORY tests mode for TImode.
This is problem for x86-64 where TImode values are commonly passed in
registers, but I don't understand what is the reason of the test for
i386 anyway and I believe we can simply drop it wihtout any change in
generated code, so the question is why it came in at first place.
