;; NOTE: Assertions have been generated by update_lit_checks.py --all-items and should not be edited.
;; As in monomorphize-types.wast, test in both "always" mode, which always
;; monomorphizes, and in "careful" mode which does it only when it appears to
;; actually help.
;; This file specifically tests that we optimize constants in MVP mode (most
;; of the pass benefits from other features, but we should still do work in
;; MVP).
