a69fd90358 - Split Dominators.h into Dominators.h & PostDominators.h

352eef717d Emit an obnoxious warning message for bytecode that includes load/store 
instructions that use indexing.  Convert them transparently into a pair
of instructions.

6d49292003 - Change constant printing to be better integrated with the rest of the

41661fdb2e - ConstantPointerRefs are now automatically removed from the module table 
when they are destroyed, which makes Constant::destroyConstant an actually
    useful external interface.  Expose these methods publicly.
  - Implement destroyConstant on ConstPointerNull so that destroyConstant can
    be used on any derived type constant safely.

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.

    ResolvedVal ::= ConstExpr this allows constexprs to be used in PHI nodes

85af131d9e Unary Not (boolean and bitwise) is no longer a separate LLVM instruction 
but is instead implemented with XOR.  Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees.  But these tree nodes are now binary, not unary.

b9a7793ecb Avoid creating 'load X, 0' instead of just 'load X' 
This _trivial_ change causes GCSE and LICM to be much more effective at
hoisting loads.  Before it would not be able to eliminate 'load X' if there
was just a dominating 'load X, 0' because the expressions were not identical.
