Lots of things might break in LLDB if the `LineEntry::IsValid()` changes. `LineEntry` objects are used for single stepping as those rely on address ranges for doing this stepping and if a `LineEntry` claims it is valid, we might try to single step with no valid address range. I worry that this change might break a lot of things in LLDB.
