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.  :)

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.

eae45cf44b 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.

16addf87bf 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.

57bd796604 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.

8d1dbd2134 Emit & read more compressed bytecode by not emitting a bytecodeblock for 
each basic block in function.  Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions.  This
saves a fairly substantial chunk of bytecode space.  In stripped, sample
cases, for example, we get this reduction in size:

197.parser: 163036 -> 137180:  18.8% reduction
254.gap   : 844936 -> 689392:  22.6%
255.vortex: 621724 -> 528444:  17.7%

...

Not bad for something this simple.  :)  Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.

9b527704f7 Add an option to enable the SSA based peephole optimizer. 
Eventually this pass will provide substantially better code in the interim between when we
have a crappy isel and nice isel.  Unfortunately doing so requires fixing the backend to
actually SUPPORT all of the fancy addressing modes that we now generate, and writing a DCE
pass for machine code.  Each of these is a fairly substantial job, so this will remain disabled
for the immediate future.  :(
