Subject: Revert "Reland "[Clang][SemaCXX] Add unused warning for variables
 declared in condition expressions""

This causes a lot of warning in sanitizer build:
https://lab.llvm.org/buildbot/#/builders/258/builds/5424
https://lab.llvm.org/buildbot/#/builders/36/builds/36560

This reverts commit 8e329caa944c377c51ef567d5aa67cfac9ffd0fa.
