P0292 defines the notion of "discarded statement" which is almost but

information about being in a discarded statement from the parser into
saved_scope. I've also added a test for a couple of cases that
demonstrate why we can't just use cp_unevaluated_context.

This is going to behave differently on 32 and 64 bit HW. Is that intentional?
(If so, a comment would be nice)
Indeed I see this test failing when testing aarch64 with -mabi=ilp32.
