[PATCH] D24854: [SROA] Drop lifetime.start/end intrinsics when they block promotion.

[Vitaly Buka via llvm-commits]

If this patch can wait a coupe of days I can investigate performance regression and amount of fixed false negatives.
It this is urgent then probably safe to do as suggested, with false-negatives, but without the risk of significant performance regression in Asan.
