Annotation attributes may be attached to a function to mark it with custom data that will be contained in the final Wasm file. The annotation causes a custom section named "func_attr.annotate.<name>.<arg0>.<arg1>..." to be created that will contain each function's index value that was marked with the annotation. A new patchable relocation type for function indexes had to be created so the custom section could be updated during linking.
