http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html shows -ftree-dse as an
optimization enabled by -O / -O1, but doesn't document it below.

Per tree-ssa-dce.c:
A dead store is a store into a memory location which will later be
overwritten by another store without any intervening loads. In this
case the earlier store can be deleted.
