Problems with lists of tuples of non-nil classes

[bradcray]

Summary of Problem

Lists whose elements are tuples containing non-nil classes don't seem to be working as hoped for, either causing problems at compile-time or surprises at execution-time.

Steps to Reproduce

Associated Future Test(s):
test/library/standard/List/classLists/listOfTupleOfClass2.chpl #15181
test/library/standard/List/classLists/listOfTupleOfClass3.chpl #15181

Configuration Information

• Output of chpl --version: chpl version 1.21.0 pre-release (0fabc0fc93)

I ended up having to remove the .bad file for listOfTupleOfClass3.chpl because it wasn't dependable, but for historical reference, it was:

[(1, {x = 5}), (2, {x = 5}), (3, {x = 5}), (4, {x = 5}), (5, {x = 5})]
