i think we need two diagnostics for clarity. vector args use a concrete clang type, so "argument %0 must be of type %1" formats correctly (e.g.` __vector unsigned char`). integer args use a type category (`"integer type"`), and using the same wording results in awkward output like `of type integer type`. keeping separate diagnostics preserves correct grammar and clearer user-facing errors.
