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.

uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT.

When a node value is only used by a CopyToReg, use the user's dest. This should not be restricted to nodes that produce only a single value.

Move some key maps from std::map to DenseMap.  This improves the time to optimize Anton's testcase from 17.5s
to 15.7s.

Use a cheaper test, delaying calling find_leader() until we know that it's necessary.  This improves
the time to optimize Anton's testcase from 21.1s to 17.6s.
