Florian Hahn 4414d94c30 [DSE,MSSA] Eliminate stores by terminators (free,lifetime.end). ... This patch adds support for eliminating stores by free & lifetime.end calls. We can remove stores that are not read before calling a memory terminator and we can eliminate all stores after a memory terminator until we see a new lifetime.start. The second case seems to not really trigger much in practice though.
