r337887 started using memset for automatic variable initialization where sensible. A follow-up discussion leads me to believe that we should better test automatic variable initialization, and that there are probably follow-up patches in clang and LLVM to improve codegen. It’ll be important to measure -O0 compile time, and figure out which transforms should be in the frontend versus the backend.

This patch is just a test of the current behavior, no questions asked. Follow-up patches will tune the code generation.
