fixed #1971

Ah, this makes cosim unhappy, I'll add DynaRec support in this PR then.

This should be done for the SIMD instructions too, but it can be delayed to the point when we add fastnan emulation for 0F opcodes, I guess.

tricky one. I guess the NAN_PROPAGATION macro will not work for AVX 3-operands type of opcodes. But that's for later.
