History
Chris Lattner 6d8fbef015 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.
