Subject: Silence -Wnon-virtual-dtor in llvm-stress.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=67076a91cf5572ae75680b48f507a066e7ea36d4;p=oota-llvm.git

Silence -Wnon-virtual-dtor in llvm-stress.

This was making it hard to scan my builds for new warnings. The
warning still fires with ToT clang. But if my workaround is unnecessary
for whatever reason, feel free to revert.
