Currently, a load from an alloca that is used in as single block and is not preceded by a store is replaced by undef. This is not always correct if the single block is inside a loop. Fix the logic so that: 1) If there are no stores in the block, replace the load with an undef, as before. 2) If there is a store (regardless of where it is in the block w.r.t the load), bail out, and let the rest of mem2reg handle this alloca.
