733ff7bbc0 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.

1eaba31f12 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.

629311ca52 Change the peep for EXTRACT_VECTOR_ELT of BUILD_PAIR to look for 
the new CONCAT_VECTORS node type instead, as that's what legalize
uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT.
