Alex Hoppen c6c40de73d [IDE] Pass a SourceRange instead of a CharSourceRange in SemaAnnotator::passReference ...

Most `SemaAnnotator`s don’t actually care about the char source range. Instead, they only care about the start location of the reference, which is also included in `SourceRange`. Computing a `CharSourceRange` from a `SourceRange` is kind of expensive because it needs to start a new lexer.

To avoid this overhead, pass `SourceRange` to `SemaAnnotator::passReference` and related functions and let the clients compute the `CharSourceRange` when needed.

This reduces the overhead of index-while-building by about 10%.
