b1a83bfd26 - started with cleanup and separation of DECORATE code.
* everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation.
 * a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.

b14f768b68 Fix FxPick code emission
- Fixed: Integer constants passed to pick() need to manually generate load
  instructions, since FxConstant::Emit() will just return a constant
  register with its value.
- Fixed: VMFunctionBuilder::RegAvailability::Reuse() didn't actually
  calculate a proper mask. Also added another assert to this function.

- Added register reuse to VMFunctionBuilder for FxPick's code emitter.
- Note to self: Need to reimplement IsPointerEqual and CheckClass, which
  were added to thingdef_function.cpp over the past year, as this file no
  longer exists in this branch.

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.

38d7b7d203 - Fixed errors and warnings when compiling with GCC. (Unfortunately, the VC++ debug builds
become ungodly slow when using mods with complex DECORATE. The GCC debug builds run just
  fine, however. Hopefully this is something that can be fixed later with an assembly-optimized
  version of the main VM loop, because I don't relish the thought of being stuck with GDB
  for debugging.)
- Fixed: The ACS_Named* action specials were erroneously defined as taking strings instead of
  names.
- Fixed: Copy-paste error caused FxMultiNameState::Emit to generate code that called
  DecoNameToClass instead of DecoFindMultiNameState.
- Updated FxActionSpecialCall::Emit for named script specials.
- Fixed inverted asserts for FxMinusSign::Emit and FxUnaryNotBitwise::Emit.

e1a2f3b546 - Added the TAIL instruction to perform a CALL and a RET in the same instruction. The called
function will pass its results directly to this function's caller. Eventually, this should
  be changed to do a proper tail call for scripted functions.

reference.

126c738116 - Added PARAMI for the common case of passing an integer constant to a function.
- Made FxParameter::Emit free its operand's register.

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.
