This cannot be fixed at the CTU context level. it must be fixed within the
`index` library, namely somewhere below `generateUSRForDecl`.
Please also explore if it would conflict with ObjectiveC interface
declarations; some of those can have `-` and `+` signs in their declaration,
which makes me worried about accidental mangling conflicts.
