;; for different shapes of a pointer+offset. Constant pointers are
;; resolved early; large offsets are folded early using explicit code
;; with an overflow check (but "large" depends on 32-bit vs 64-bit);
;; wait/notify fold offsets early regardless; zero offsets lead to
;; tighter code with variable pointers; and don't get me started on
;; alignment checks. These test cases are not exhaustive but aim
;; to test at least some things.
