497e19aee0 Remove CLocalVars data structure entirely, instead of building stuff and 
then printing it out, just print as we go.

7683a12e20 Simplify code by removing InstLocalVarsVisitor, replacing it with a simple 
inst_iterator.

1f02c8910a * Clean up how PHI nodes are handled 
* Correct global variable references
* Fix loads & stores with zero indices
* Do not emit an else part of a branch if there is no code (no phi node
  and a fallthrough branch), makes code more readable to get:
  if (l2_cond240) {
    goto l13_bb10;
  }

with no else{} branch

2d05a1acb0 * Remove dead "constant printing" code 
* Mangle names with only a prefix so that they are easier on the eyes.
* Put spaces around binary operators with low precedence to make them easier to read
* Don't prefix function names with &, although it's correct, it's unnecesary and
  easier to read without it.

b9a6634466 * Finish the implementation of isEdgeFeasible this fixes bug: 
test/Regression/Transforms/SCCP/2002-05-02-EdgeFailure.ll
* SCCP now preserves the CFG:  It leaves conditional branches the way they
  are in the program, not simplifying them.  A seperate pass should eliminate
  the potentially dead basic blocks and edges in the CFG.

59f0ce2a41 * Enable SCCP debugging to be turned on with a simple change of #define 
* Change worklist to a set so that duplicates cannot happen
* Add support for the invoke instruction
* Avoid marking store and free instructions as overdefined, since they
  cannot produce a value anyway.
* Inline the OperandChangedState implementation
* Add isEdgeFeasible in preparation to fix a bug.  Right now it behaves
  exactly as before.
* Remove obsolete comment about constant pools
