956d754804 DECORATE cleanup
- Remove some ExpVal stuff that wasn't used.

2f7183b937 Use PField instead of PSymbolVariable for DECORATE expressions
- The type systems used by PField and FxExpression are completely
  incompatible, but I think I got the differences taken care of as far
  as ParseNativeVariable(), ParseUserVariable(), and FxClassMember are
  concerned.
- Support for declaring native bool variables has been removed for the time
  being. It wasn't used anyway.
- Removed PSymbolVariable.

4f528e3832 Remove lax from FCompileContext
- It's always set to true these days, so let's get rid of it.

09c902ce55 Remove isconst from FCompileContext.
- It's not used anymore, so keeping it around is pointless.

58f088c1ab Remove FxExpression::EvalExpression() entirely
- For the purposes of getting constant values from expressions, the only
  class where Resolve doesn't duplicate the functionality of
  EvalExpression was FxConstant. So, every other class has had its
  EvalExpression taken away, and FxConstant has had it renamed to GetValue.

241622300e Removed some EvalExpression implementations
- Removed EvalExpression() implementations from some subclasses of
  FxExpression that don't make any sense in the context of evaluating a
  constant value.

2c24e7f9c6 Remove self pointer from FxExpression::EvalExpression()
- Every place that calls this now (which are all in thingdef_parse.cpp)
  passed NULL for the self pointer, so it was superfluous to have around.

6e88529324 - Added a RETI instruction for returning 15-bit signed immediate values.
- Changed Actor's Damage property into an actual function. All access to the damage property
  must now be done through GetMissileDamage. actor->GetMissileDamage(0, 1) is equivalent
  to the former actor->Damage, for the case where actor->Damage was not an expression. (I
  suppose I will probably need to make a thunk for DECORATE expressions that want to read it.)
- Cleaned up some decorate expression evaluation functions that are no longer used.

f88f601230 - Removed the third parameter from dumpclasses when it was restricted it to Actors, because
I have no idea what that was all about.
- Got rid of FActorInfo and merged it into a new PClassActor.

7ea11cd169 - Allocate VM script code and constants in a single block for better locality of
reference.

c424c61ffc - Added fixed registers that won't be freed automatically, so that parameters
can actually be used. In the end, all temporaries should be assigned to
  unique virtual registers, and a register allocator can alias them to real
  registers, but as long as we don't do any CSE, this is good enough for now.

85cc335725 - Added dummy code generation for states that pass parameters to action functions.
Currently, they're only good for disassembly and pasting into a proper text editor
  for viewing.
- Fixed some problems with the FxExpression emitters that were revealed by actually
  using them on the standard actors.

3001708d16 - Added some code for generating VM code from FxExpressions. This is completely untested, since
it isn't even used anywhere yet. In retrospect, I probably should have targeted an intermediate
  representation and done codegen with that instead, since that would be something I can reuse.

e8d1416d81 - Added the frandom decorate function, which is exactly like random except
that it works with floating point instead of integers.

f8c38e5f54 - Made several DECORATE errors which do not involve parsing non-fatal.
- Added a static error counter to FScriptPosition class.
- Changed initialization of actor class type properties: fuglyname is gone as
  is the postprocessing in FinishThingdef. Instead an empty placeholder class
  is now created when a class is first referenced and this placeholder is later
  filled in. 
- Added option to replace backslash with '^' in state frame definitions because
  the backslash is just causing too many problems because it's also an escape
  character.

d753d41752 - Added NULL checks to all places where class names are passed as DECORATE
parameters.
- All DECORATE parameters are passed as expressions now. This change allows
  for compile time checks of all class names being used in DECORATE so many
  incorrect definitions may output warnings now.
- Changed DECORATE sound and color parameters to use expressions.
- Changed: S_StopChannel now resets the actor's sound flags. The previous bug
  made me think that delaying this until FMod calls the end of sound callback 
  may simply be too late.

b455227342 - Added a proper function parser to the expression evaluator and converted
sin/cos and action specials to use it. The old evaluator is gone now.
- fixed some GCC problems with autosegs.

b9afb78523 - Added native variables to expression evaluator and replaced the previous
handling of actor variables in expressions with it.
- Added support for floating point constants to DECORATE expression evaluator.

7312e6a621 - Added a global symbol table and changed DECORATE parser to put its global
symbols there instead of into AActor.
- Changed the expression evaluator's floating point precision to double.
- Started rewriting the DECORATE expression evaluator to allow more flexibility.
  All the operators use the new functionality but functions, variables and
  constants are yet to be redone.
  While doing this rewrite I noticed that random2 was always evaluated as const.
  This got fixed automatically.
