Chris Lattner 6c237bcdf2 Do not insert one entry PHI nodes in split exit blocks!

Brian Gaeke ddc088a9e4 Check in the llvm-native-gcc script, which I use in the process of 
debugging front-end miscompilations.

Chris Lattner 720348331c Add a new testcase which breaks the sinker because the loop canonnicalization 
pass does not do a canonnicalization that the sinker wants.

are sunk

Chris Lattner 65c1193d55 Refactor code a little bit, eliminating the gratuitous InstVisitor, which 
should make subsequent changes simpler.  This also allows us to hoist vaarg
and vanext instructions

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

Chris Lattner 198e620752 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.  :)

  The second exposes what was previously JIT specific state to general clients

Chris Lattner a7b6f3ab9c 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.

Chris Lattner d1ea9cd345 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.

Chris Lattner 00f5167693 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.

Chris Lattner 31b77bbf7e Rewrite dominators implementation. Now domset is constructed from immdom, 
instead of the other way around.

Tanya Lattner c970a38824 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.
