Florian Hahn 80970ac875 [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.
