52e20b0977 * 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.

6e6026b465 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

8cdc6b726a - 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.

bbd4b303e3 There is no way to guarantee that constants are not forward referenced.

197.parser benchmark to be built

69da5cf261 - Change Function's so that their argument list is populated when they are

    now a Function ALWAYS has a populated argument list.

7473413072 - 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.

e8e4605021 Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr
