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

cd6bbd3823 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.

03980a2b30 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.

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.

b5027095e5 - Eliminated the deferred symbol table stuff in Module & Function, it really
wasn't an optimization and it was causing lots of bugs.

dd74dc44b6 - 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.

33988dc76d 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

82f54dca49 - 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.

f3d49adf85 - Finally nailed: test/Regression/Assembler/2002-08-16-ConstExprInlined.llx
- ParseConstantPool was resolving reference to value using the function
      slot # instead of the global slot #.
  - Bytecode reader changes:
    - Remove the failure<> template from Bytecode Reader
    - Remove extraneous #includes
    - s/method/function/ a bit
    - Eliminate the fwdRefs class that just added abstraction where it was not
      needed, making things more complex.
    - Use a vector instead of a list for function signatures.
