Ryan Houdek e3d7161ac5 FEXCore: Override x87 precision control when necessary ...

According to the documentation for x87 FCW precision control, this only
affects fadd*, fsub*, fmul*, fdiv*, and fsqrt. FEX was incorrectly
reducing precision for all x87 operations.

Precision is ignored for the following x87 ALU operations:
- fabs
- fscale
- fprem{1,}
- fcos
- fsin
- ftan
- fyl2x
- fyl2xp1
- fpatan
- fsincos
- Plus any operations just doing data movement and conversions

Next commit adds unittests to ensure this is correct for each
instruction.
