[PATCH] D152495: [Clang][SemaCXX] Add unused warning for variables declared in condition expressions

[Mikhail Goncharov via Phabricator via cfe-commits]

goncharov added a comment.

due to this change we have a enourmous number of new warnings, on the other hand -Wunused-variable is a valuable warning. I am not sure what is the policy and best practices for warnings but maybe there is a possiblity to make a transition period for enabling this type of warning separetely and to allow updating existing code?
