Also, the assert could never fire due to || instead of &&.

Move to using the EquivalenceClass ADT. Removes SynSets.

If a branch's condition has become a ConstantBool, simplify it immediately.
Removing the edge saves work and exposes up more optimization opportunities
in the pass.
Add support for SelectInst.

Teach the coallescer to coallesce live intervals joined by an arbitrary
...
number of copies, potentially defining live ranges that appear to have
differing value numbers that become identical when coallsced. Among other
things, this fixes CodeGen/X86/shift-coalesce.ll and PR687.
