Flyinghead b70c2791b2 dynarec: proper ftrc implem. (arm32/64) Use double for fipr/ftrv
Use double for canonical FIPR and FTRV on all platforms.
Fix interpreter implementation of FTRC.
Fix canonical implementation of cvt_f2i (FTRC).
arm32: use Vfma instead of Vmla for FMAC. Vfma does not a fused
muliply-add, Vmla doesn't.
arm32: Use canonical implementations of FIPR and FTRV.
arm32,arm64: Correct implemetation of cvt_f2i (FTRC)

Fixes desync with NBA 2k1/2k2 online games.

flyinghead 7308f9a704 sh4: dont change host rounding mode in Sh4_int_Reset()
Don't change host rounding mode in Sh4_int_Reset(), which is typically
called from the UI thread.
Set rounding mode to default before calling renderer (single-thread
mode), restore it before returning.
Fixes issues with dx11 shaders compilation: rounding mode affects
inexact literal float values.
