Also make sure to clean up any PHI nodes that are inserted which are pointless.

647b7d8869 Implement: test/Regression/Transforms/TailCallElim/accum_recursion.ll 
We now insert accumulator variables as necessary to eliminate tail recursion
more aggressively.  This is still fairly limited, but allows us to transform
fib/factorial, and other functions into nice happy loops.  :)

be2b3fb417 Cleanup and restructure the code to make it easier to read and maintain. 
The only functionality change is that we now implement:
  Regression/Transforms/TailCallElim/intervening-inst.ll

Which is really kinda pointless, because it means that trivially dead code
does not interfere with -tce, but trivially dead code probably wouldn't be
around anytime when this pass is run anyway.

The point of including this change it to support other more aggressive
transformations when we have the analysis capabilities to do so.

d4abe8d28a The recalclulate method was a nasty hack that was once used by the -cee pass, 
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

9eeb35760f Completely rewrite domset, idom, and domtree implementation. Now it is based 
on the algorithm for directly computing immediate dominators presented in this
paper:

  A Fast Algorithm for Finding Dominators in a Flowgraph
  T. Lengauer & R. Tarjan, ACM TOPLAS July 1979, pgs 121-141.

This _substantially_ speeds up construction of all dominator related information.
Post-dominators to follow.

0499e53fe5 New command line parsing. This isn't as perfect as I would have liked. The CommandLine Library needs to be extended, in order to parse the options and allow for optional dashes. In addition, the help option isn't correct since I do the parsing mostly myself. But this is in the ocorrect ar format.
