[PATCH] D45310: Warn about memcpy'ing non-trivial C structs

ahatanak created this revision. ahatanak added a reviewer: rjmccall. Issue a warning when non-trivial C structs (structs with '__weak' or '__strong' fields) are copied or initialized by calls to memset, bzero, memcpy, and memmove. This is similar to gcc's -Wclass-memaccess warning. It might be b
