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 f419786584 Fix sh4 FTRC op to use correct positive cutoff value.
Fix for interpreter, common dynarec and x86 rec.

Fixes wrong car color in Tokyo Xtreme Racer car selection screen.

Flyinghead f13b366e8d Set the value for NaN according to the SH4 specs
The SH4 sets the signaling bit to 0 for qNaN: 7fbfffff instead of the
usual 7fffffff. Same games seem to rely on this.
Fixes Fur Fighters freeze and missing geometry in game.

Flyinghead ea35eeb728 Fix FTRC op in both interpreter and dynarec with respect to Inf and NaN
The -ffast-math gcc option implies the -ffinite-math-only option, which
produces wrong results with Inf and NaN. Use integer math to detect the
sign of float numbers in FTRC to avoid these issues.
Also the upper cut off value for conversion was apparently wrong.
Also fixed the x86 dynarec but not tested.
Fixes wrong car color in Tokyo Xtreme Racer car selection screen.

Stefanos Kornilios Mitsis Poiitidis 61394d7a44 shil: Disable external assembly implementations
Using external function pointers is broken after the rec-cpp structural changes,
and relatively low priority so disabled for now.

Stefanos Kornilios Mitsis Poiitidis fb55e7f6f8 sh4/canonical: Provide impls for sync_sr and sync_fpscr
This shouldn't be a requirement as directly using shil_cf_ext should work,
but for some reason if I don't msvc optimizes the functions out.

Stefanos Kornilios Mitsis Poiitidis b1f7015a98 rec/cpp: Mostly fully direct specialized dispatchers

- Add more direct handlers
- Add prints if a direct handler isn't found
- Remove multiple indirect handlers, leave them for fallback
