LGTM
In some cases, we could prove that the access is either in-range, or not based on the alloca. (For example, given an alloca "a" and an access "min(a,b)+1", the pointer is either "a+1", or "b+1". "a+1" is in range, and "b" is unrelated to the alloca, so the access is safe.) But it seems unlikely to be important.
