Test legacy mangling of bool, char and integer constants
The existing v0 tests have been slightly adjusted for compatibility with legacy mangler, which requires an item to have an ancestor in a value namespace or a type namespace to produce a symbol for it. In v0 mangling this results in an extra `Nv` component.
