Details
For example when we generate the CacheIR, we can assert argument types/count instead of checking for them, similar to what we do in SelfHosting.cpp. We also don't need the emitNativeCalleeGuard guard because we can rely on self-hosted code not calling these intrinsics in weird ways.
We should still document each of these places to prevent copy/paste issues. Also it can be annoying to assert isInt32 because in some cases we might get integers stored as doubles.
