Partially revert "qfloat16: suppress the tables if FP16 is supported by the CPU"

Browse Source 
This reverts the x86 F16 part of commit
9649c41ed9. Unfortunately, it is perfectly
valid to compile coe without F16C an link to a QtCore that was compiled
with it. That's the case in Clear Linux where there's
/usr/lib64/libQt5Core.so.5 and /usr/lib4/haswell/libQt5Core.so.5.
