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.

Do NOT inline self recursive calls into other functions. This is causing the

pool allocator no end of trouble, and doesn't make a lot of sense anyway. This
does not solve the problem with mutually recursive functions, but they are much less common.

Checking in Chris's suggestions:
...
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.
