Eli Friedman 05a71b0a6d [ScalarEvolution] Fix overflow in computeBECount. 
The current implementation of computeBECount doesn't account for the
possibility that adding "Stride - 1" to Delta might overflow. For almost
all loops, it doesn't, but it's not actually proven anywhere.

To deal with this, use a variety of tricks to try to prove that the
addition doesn't overflow.  If the proof is impossible, use an alternate
sequence which never overflows.
