Sanjoy Das 6e9b355cc9 Revert "[SCEV] Add nuw/nsw to mul ops in StrengthenNoWrapFlags" ...

This reverts r334428.  It incorrectly marks some multiplications as nuw.  Tim
Shen is working on a proper fix.

Original commit message:

[SCEV] Add nuw/nsw to mul ops in StrengthenNoWrapFlags where safe.

Summary:
Previously we would add them for adds, but not multiplies.
