Previously, the function names were stored in `std::string` and were often created dynamically (especially when the function just output a constant). This resulted in a lot of overhead. Now the function name is just a `const char *` that should be statically allocated. This is good enough for the majority of cases. If a multi-function needs a more dynamic name, it can override the `MultiFunction::debug_name` method. In my test file with >400,000 simple math nodes, the execution time improves from 3s to 1s.
