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

543d622ef7 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.  :)


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10332 91177308-0d34-0410-b5e6-96231b3b80d8

7152da38ef 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.

7d275f459b Avoid building data structures we don't really need. This improves the runtime 
of a test that Bill Wendling sent me from 228.5s to 105s.  Obviously there is
more improvement to be had, but this is a nice speedup which should be "felt"
by many programs.

8fce16ef1a Do not return success after checking only the FIRST USE of a gep instruction. 
Instead, check all uses.
This fixes bug: ScalarRepl/2003-09-12-IncorrectPromote.ll
This also fixes the miscompilation of Ptrdist/bc
