edda1af35a Make LICM itself a bit more efficient, and make the generated code more efficient too: don't insert a store in every exit block, because a particular block may be exited to more than once by a loop

aaaea51090 Implement instruction sinking out of loops. This still can do a little bit
better job, but this is the majority of the work.  This implements
LICM/sink*.ll

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.

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.  :)

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.

984e11792f 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.
