There was a problem hiding this comment.
note: if we don't want to update VB, i'm fine with that and can revert this. But it seems sensible to me. It also means we can optimize GetFirstLocation in the future (like we have for C#) and get the benfit for vb as well automatically.

Fixes #29707
This is faster in C# for some symbols as it does not need to realize arrays to wrap a single location for many symbols. There is also GetFirstLocationOrNone if you need to call on a symbol which does not have locations.
