Jakob Stoklund Olesen ec096b4925 Remove the late DCE in RegisterCoalescer.
Dead code and joined copies are now eliminated on the fly, and there is
no need for a post pass.

This makes the coalescer work like other modern register allocator
passes: Code is changed on the fly, there is no pending list of changes
to be committed.
