Implemented for x86/x64 and ARM64.
Should fix reported issues with unbeatable bosses in Metal Gear on iOS (which can only use the IR interpreter, so effectively re-fixing #2845 and also #3988 on this backend.
Also I'm noticing that our IR interpreter uses suboptimal methods to convert float to int, some inline assembly would help. However, I'll leave fixing that for a future change.
