This patch adds a checker checking `std::string` operations. At first, it only checks the `std::string` single `const char *` constructor for nullness. If It might be `null`, it will constrain it to non-null and place a note tag there. Reviewed By: martong Differential Revision: https://reviews.llvm.org/D111247
