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.

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.
