[PATCH] D100464: [DSE] Remove stores in the same loop iteration

[Changpeng Fang via Phabricator via llvm-commits]

Right. If we manually LICM'ed the load/stores in group 1 and group2 (with something like sum_i),
we will see the higher register pressure. Further, if we intentionally insert dead stores to store
the intermediate sum_is, the register pressure  can be lowered. Some later passes should be responsible.
