62331c44ab There is no need for BytecodeParser to be an AbstractTypeUser. Instead, it
can just use PATypeHolders

222df3cfc5 Define the instance variable Buffer, not the automatic variable Buffer.
This was causing us to munmap random stuff, which is obviously bad.

055804accd Suggestions made by Chris:
* Instead of a #define, use inline function
* Fix the name on the #define, errr... now inline function to be more logical:
  it doesn't CHECK the alignment, it PERFORMS the alignment
* To get string name of a Type*, use getDescription(), not getName()

41f2a38c92 * 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

839f5a9077 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.

dd194d3844 * 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.

dd74dc44b6 - Fix a really nasty bug in the bytecode reader that caused it to fail
