This is V3 of the 4 series patchkit to address various DSE issues.
The various comments from the V2 patchkit have been addressed and I
believe the net result is cleaner and more compile-time efficient.
The major changes were a move to using sbitmaps, only allowing the live
sbitmap once per invocation of the DSE optimizer, and more efficient
trimming computations.
Again, patches #1 and #2 seem appropriate to me at this stage in our
development cycle. #3 and #4 are harder to justify.
There's dependencies as we walk forward in the patch kits. Each patch
has been bootstrapped & tested with its previous patch(es).
