Introduces a utility function which allows obtaining a pointer to the exception data held behind an std::exception_ptr if the data matches the requested type. It can be used to implement manual but concise try..catch chains. The `try_catch` has the best performance when used with libstdc++ as it uses the stdlib specific functions for simulating a try..catch without having to actually throw. For other stdlibs, the implementation falls back to a throw surrounded by an actual try..catch.
