a96c1f665a Handle the case where an entire structure is freed, and its dependency is a store to a field within
that structure.

Also, refactor the runOnBasicBlock() function, splitting some of the special cases into separate functions.

b77c457cc8 Add FastDSE, a new algorithm for doing dead store elimination. This algorithm is not as accurate
as the current DSE, but it only a linear scan over each block, rather than quadratic.  Eventually
(once it has been improved somewhat), this will replace the current DSE.

NOTE: This has not yet been extensively tested.
