[DSE] Don't DSE stores that subsequent memmove calls read from
Summary:
We used to remove the first memmove in cases like this:
memmove(p, p+2, 8);
memmove(p, p+2, 8);
which is incorrect. Fix this by changing isPossibleSelfRead to what was most
likely the intended behavior.
Historical note: the buggy code was added in https://reviews.llvm.org/rL120974
to address PR8728.
