67db5fd7 - [clang] Add Bytes/Columns types to TextDiagnostic (#165541)

[clang] Add Bytes/Columns types to TextDiagnostic (#165541) In `TextDiagnostic.cpp`, we're using column- and byte indices everywhere, but we were using integers for them which made it hard to know what to pass where, and what was produced. To make matters worse, that `SourceManager` considers a "column" is a byte in `TextDiagnostic`. Add `Bytes` and `Columns` structs, which are not related so API using them can differentiate between values interpreted columns or bytes.
