[DSE] Support redundant stores eliminated by memset.
This patch adds support to remove stores that write the same value
as earlier memesets.
It uses isOverwrite to check that a memset completely overwrites a later
store. The candidate store must store the same bytewise value as the
byte stored by the memset.
