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.

OpenBSD 7.2 patches (#953)
* OpenBSD: BSS is immutable so mark it as mutable so that mprotect RWX works

see: mimmutable(1)
bc009f82ea

* OpenBSD does not have mcontext_t

<signal.h> provides `typedef struct sigcontext ucontext_t;'.
take register names from <machine/signal.h>, which provides struct
sigcontext.

see:
1a13d3ae4e

* OpenBSD uses major.minor for shared libs, so properly dlopen libGL.so

* OpenBSD remove redefinition of swap16

* OpenBSD: SDL2 controller detection

Use sdl_open_joystick() to open controllers on startup instead of
SDL_JOYDEVICEADDED event, which never gets detected.

* OpenBSD does not have mcontext_t but linux does
