850055a766 Add evaluation of constant unary and binary expressions
- Added ZCCCompiler class as a place to generate IR and symbols from an
  AST. Right now, all it does is simplify constant expressions into
  constant values.
- Do type promotion on the AST where appropriate.
- Added true and false tokens to the parser driver.

11b588de4a Add names for fallback tokens.
- Fixed: When falling back to the IDENTIFIER token, the identifier it
  would get was undefined, because it never got initialized.

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.

2d139f3846 - DoParse() now writes out the parsed AST for the input file to <file>.ast.
Maybe TODO: Find a simple LISP pretty printer that isn't written in LISP so that the output
  isn't all on one big long line.
- zcc-parse.lemon now returns the complete AST through the parse state.
- Fixed crash in PrintEnumNode().

081ebbb64b - I have decided to opt for simplicity over C-like-ness and group array sizes with the rest
of the type declaration rather than split it up after the variable name.
- More AST work. At this rate, maybe I'll finally be building a complete AST by the end of the
  month!

c043627cc1 - Some abstract syntax tree creation stuff. (Plus some tentative type creation stuff that made
me realize I would be better off creating a type-agnostic AST for the entire input instead
  of trying to tentatively create types before they're seen.)
