66e6dd1cab a32_emit_x64: std::move A32::UserConfig in the constructor 
This avoids a few redundant atomic increments and decrements,
considering the UserConfig instance contains a std::array of
std::shared_ptr<Coprocessor> instances.

895db36543 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.
