omitNeedlessWords: Rename helper: omitTrailingTypeNameWithSpecialCases
omitNeedlessWords: Rename helper: omitTrailingTypeNameWithSpecialCases

Previously this was /also/ called 'omitNeedlessWords'. Rename it to
avoid confusion and better describe the particular step it's taking.

I don't love the "with special cases" but I think it's important to
note that this isn't an exact parallel of matchLeadingTypeName.
