Bring the typed expression representation of a coindexed reference up to F'2023, which removed some restrictions that had allowed the current representation to suffice for older revisions of the language. This new representation is somewhat more simple -- it uses a DataRef as its base, so any subscripts in a part-ref can be represented as an ArrayRef there. Update the code that creates the CoarrayRef, and add more checking to it, as well as actually capturing any STAT=, TEAM=, & TEAM_NUMBER= specifiers that might appear. Enforce the constraint that the part-ref must have subscripts if it is an array. (And update a pile of copied-and-pasted test code that lacked such subscripts.)
