bcc8972356 - fixed: A preincrement of a local variable generated wrong code if passed as a function parameter.
Due to the special nature of this expression the code generator got stuck in 'address' mode and passed the address of the variable instead of its value.

d50ba4954a Fixed potential crash when calling undefined function in ZScript
The following code which uses explicit class specifier led to a crash:
class C
{
	void F()
	{
		Object.Undefined();
	}
}

b4fa95ab15 - handle state label resolution in a non-actor cpntext more gracefully.
Note that this is merely a hotfix. Properly handling this to allow universal use of state scopes will require more work in cases where a scoped state is being accessed through a non-self pointer.

cd180d29c7 - block direct use of 'new' for DObjects.
This is to ensure that the Class pointer can be set right on creation. ZDoom had always depended on handling this lazily which poses some problems for the VM.
So now there is a variadic Create<classtype> function taking care of that, but to ensure that it gets used, direct access to the new operator has been blocked.

This also neccessitated making DArgs a regular object because they get created before the type system is up. Since the few uses of DArgs are easily controllable this wasn't a big issue.

- did a bit of optimization on the bots' decision making whether to pick up a health item or not.

98dab9c4b9 - took PTypeBase and all its subclasses out of the DObject hierarchy.
- moved scope flag to a new variable that is specific to PType instead of hijacking the ObjectFlags for this.

b2d944974e - first stage of simplifying the type system.
Let's use inline checkers in PType instead of constantly having to do clumsy IsKindOf checks etc. Once complete this also means that the types can be taken out of the class hierarchy, freeing up some common names.

fc9e304189 - separated class descriptors from VM types.
Combining these two groups of data has been the cause of many hard to detect errors because it allowed liberal casting between types that are used for completely different things.

96631e8808 - make PClass not inherit from PStruct.
Having these two types related can cause problems with detection in the compiler because for some parts they need quite different handling.
Common handling for the fields has been moved into PSymbolTable but overall redundancy was quite minor as both types share surprisingly little functionality.

0d7b7d6ab1 - merged PStruct and PNativeStruct.
There were exactly 4 places in the code that checked for the difference, this is better done with a flag.

6308251084 - added a FindSymbol wrapper to PClass so that other code does not need to access the symbol table directly.
- added an isActor utility function to codegen.cpp to simplify a few constructs.

9c9b2ccf6d - replaced more dyn_casts and checks for RUNTIME_CLASS(PClassActor)
It is preferable to use IsDescendantOf wherever possible if we ever want to be able to separate PClass from PType.

e4d2380775 - moved all remaining fields from PClassActor to FActorInfo.
- added a few access functions for FActorInfo variables.

With PClassActor now empty the class descriptors can finally be converted back to static data outside the class hierarchy, like they were before the scripting merge, and untangle the game data from VM internals.

ef77cbd295 - stop using the ATAGs for checking pointer types in asserts.
This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere.
Note that this commit does not remove the tags, it only discontinues their use.

74faacd218 - fixed: FxVMFunctionCall::GetDirectFunction did not perform any checks on the function's self pointer and failed to report a mismatch as an error.
- also fixed two places in the code where the above caused some incorrect definitions not to be detected.

41f2f61b94 - minor VM optimization: Precalculate a function's frame size when compiling it instead of doing it each time it gets called.
This made up ca. 10% of the 'call' instruction's execution time.
