Evan Cheng a5a81d7072 Add TargetInstrInfo::isCoalescableInstr. It returns true if the specified
instruction is copy like where the source and destination registers can
overlap. This is to be used by the coalescable to coalesce the source and
destination registers of instructions like X86::MOVSX64rr32. Apparently
some crazy people believe the coalescer is too simple.
