[PATCH] D63085: Provide a fix-it hint for -Wswitch, which adds missing cases. If there are >3 cases, the inserted text will contain newlines so it will not be shown in console output (but will be applied by -fixit, available to libclang and clangd, etc).

Lifted the helper for spelling one scope from another from
SemaCodeComplete -> AST, to reuse it. It should be useful in other contexts too.
