6e9a3517f2 * Cleaned up code: 
- no more passing around a string pointer to set errors
  - no more returning booleans and checking for errors, we use C++ exceptions
* Broke functionality into 2 new classes, one reads from file, one from a stream
* Implemented lazy function streaming - the parser can read in a function at-a-time

53bd0b24f2 Remove a gross hack that was there to support bytecode files that are over a year old. 
If you still have these suckers laying around, you have GOT to rebuild them.  geeze.

55a07adc36 Allow modules to have 'any' pointer size and endianness. Luckily, we had 
some space for extra flags, so we don't need to bump the revision number.

428bf5abc9 Changes to the V2 bytecode format: 
- Null values are implicitly encoded instead of explicitly, this makes
    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:
      Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
    instead of
      Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
    which makes a lot of things simpler.

Writer changes:
  - We now explictly encode versioning information in the bytecode files.
  - This allows new code to read bytecode files produced by old code, but
    new bytecode files can have enhancements such as the above.  Although this
    makes the reader a bit more complex (having to deal with old formats), the
    writer only needs to be able to produce the most recent version.

5db8194ca9 * Bug fixes: 
- Fix problems where the constant table would not get updated when
    resolving constants causes other constants to change.

Changes to the V2 bytecode format
  - Null values are implicitly encoded instead of explicitly, this makes
    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:
      Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
    instead of
      Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
    which makes a lot of things simpler.

Changes to the reader:
  - Function loading code is much simpler.  We now no longer make function
    PlaceHolderHelper objects to be replaced with real functions.

98cf1f5d64 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

49f4242d2b - Fix a really nasty bug in the bytecode reader that caused it to fail 
reading bytecode files with > 255 types in them, but only when optimization
    is enabled.  This was caused by GCC shrinking an enum to a single byte
    instead of a whole word.

2862d2ec71 There is no way to guarantee that constants are not forward referenced. 
Handle forward referenced constants in a general way.  This fixes bug:
Assembler/2002-10-13-ConstantEncodingProblem.llx and allows the SPEC
197.parser benchmark to be built

149376dee5 - Change Function's so that their argument list is populated when they are 
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.
