Attached test case asserts on x86 debug builds.
This one triggers the (I suspect) related assertion: Assertion failure: use->virtualRegister() < graph.numVirtualRegisters(), at GreedyAllocator.h:296
Situation: a predecessor is merging the state of its left and right successors. The left side has R0=Def1, and the right side has R1=Def1. We accidentally ignored this case and Def1 became assigned to both R0 and R1. As a fix I inserted a move in the right-hand block from R0 -> R1.

I found another test case that broke this, turns out I missed a case.
