Address minor nits, plus add a test case that showcases the extra (legitimate!) warning we now get when accessing a "struct hack" field with an index that cannot be represented in associated address space.

Kudos to @aaron.ballman for spotting this one!

As a comparison, current behavior for the same test case: https://godbolt.org/z/86Wcbrz5q (only the flexible array member is flagged with a warning, the struct hacks are ignored)
