00926a6d - [SCEV][LAA] Support multiplication overflow computation (#155236)

[SCEV][LAA] Support multiplication overflow computation (#155236) Add support for identifying multiplication overflow in SCEV. This is needed in LoopAccessAnalysis and that limitation was worked around by 484417a. This allows early-exit vectorization to work as expected in vect.stats.ll test without needing the workaround.
