Nikita Popov be9889b350 [MemorySSA] Don't treat lifetime.end as NoAlias 
MemorySSA currently treats lifetime.end intrinsics as not aliasing
anything. This breaks MemorySSA-based MemCpyOpt, because we'll happily
move a read of a pointer below a lifetime.end intrinsic, as no clobber
is reported.

I think the MemorySSA modelling here isn't correct: lifetime.end(p)
has approximately the same effect as doing a memcpy(p, undef), and
should be treated as a clobber.

This patch removes the special handling of lifetime.end, leaving
alias analysis to handle it appropriately.
