Weiming Zhao 081f41bef8 Fix bug 25440: GVN assertion after coercing loads ... Optimizations like LoadPRE in GVN will insert new instructions. If the insertion point is in a already processed BB, they should get a value number explicitly. If the insertion point is after current instruction, then just leave it. However, current GVN framework has no support for it. In this patch, we just bail out if a VN can't be found.
