Making callstack resolving operational will require a little bit more effort
src/scripting/vm/jit_runtime.cpp:900:31: error: use of undeclared identifier 'frames'
src/scripting/vm/jit_runtime.cpp:903:23: error: use of undeclared identifier 'cnt'
For ad-hoc Dehacked state functions no ArgFlags are created, in this case they can just be assumed to not be relevant here, because none of these function produces reference arguments.
- disallow bool as a return value for direct native calls because it only sets the lowest 8 bits of the return register.
- changed return type for several functions from bool to int where the return type was the only thing blocking use as direct native call.

* use I_Error instead of I_FatalError to abort. I_FatalError is only for things that are not recoverable and should not be handled outside of error cleanup and rethrowing.
* only catch CRecoverableError in JitCompile. Everything else should fall through to the outermost catch block.
* Do not I_FatalError out after handling the exception locally. Just print an error and return null, indicating failure.
* The functions had no prototype and caused crashes.
* even after creating a prototype it didn't work because CreateAnonymousFunction was set up incorrectly for the case where a known return type was given.
- offloaded key list generation for alternative HUD to non-UI parts.
This change also revealed a problem with handling empty sprites in the key list so this got fixed, too.
- changed PARAM_STRING to use the passed string by reference instead of by value. The 3 instances where passing by value was needed now use PARAM_STRING_VAL.
On Windows none of this is needed, because we can generate a proper unwind frame for the JITed functions, but even on Linux, it would require manual additions to each single piece of native code that ever gets called from inside a JIT compiled function.
This is an utterly prohibitive proposition because it makes direct native calls a virtual impossibility
So, in order to get the thrown error properly presented both I_Error and ThrowAbortException will now forward to I_FatalError if it is called from inside a JIT context.
