bb93353f94 emit_x64_vector_floating_point: Correct FMA in FTZ mode 
x64 rounds before flushing to zero
AArch64 rounds after flushing to zero

This difference of behaviour is noticable if something would round to a smallest normalized number

b393e15ab6 backend_x64: Fix bugs when FPCR.FZ=1 
Bugs:
* DenormalsAreZero flushed to positive zero instead of preserving sign.
* FMAXNM/FMINNM (scalar) should perform DAZ *before* special zero handling.
* FMAX/FMIN/FMAXNM/FMINNM (vector) did not DAZ.

463b9a3d02 ir: Add opcodes for vector paired maximum and minimums 
For the time being, we can just do a naive implementation which avoids
falling back to the interpreter a bit. Horizontal operations aren't
necessarily x86 SIMD's forte anyways.
