The test is testing the injection for three vector libraries supported by the TLI (Accelerate, SVML, MASSV). The pass does not change any of the analysis associated to the function.

The inserted basicblock can have a successor that contains a PHI node whoes incoming basicblock is the inserted basicblock. Since the existing code does not handle it, it becomes a badref. if (cond1) statement if (cond2) statement successor - contains PHI node whose predecessor is cond2 --> if (cond1 || cond2) statement (BB for cond2 was deleted) successor - contains PHI node whose predecessor is cond2 --> bad ref!

Before this patch, `iterativelyFlattenCFG` could try to increment a BB iterator after that BB has been removed and crash. This patch makes FlattenCFGPass use `WeakVH` to skip over erased blocks.

Specifically, after SROA works first time, instcombine converts dbg.declare intrinsics into dbg.value. Inlining creates new opportunities for SROA, so it is called again. This time it does not handle correctly previously inserted dbg.value intrinsics.

If we see an op for the first time, Infos will be empty and we can also add it to OpsToRename. We process operands by visiting BBs depth-first and then iterate over all instructions & users, so the order should be deterministic. Therefore we can skip one round of sorting, which we purely needed for guaranteeing a deterministic order when iterating over the SmallPtrSet.

When `renameUses` function sorts `OpsToRename` (https://fburl.com/d2wubn60), the comparator assumes that the parent block of the operand has a corresponding dominator tree node. This is not the case for unreachable operands and crashes the compiler.
