Generates contract clauses of dependencies as assertions, with an option
--no-assert-contractsto disable it. This works by adding a new contract mode that outputs the original body of the function with its contract clauses asserted. During theFunctionWithContractPass, we use this closure, unless--no-assert-contractswas passed, in which case we use the regular body.I'm omitting a description of why this is useful from the PR description--there's one in the module documentation, and I want that to be a self-contained explanation (i.e., if something is unclear, I want to fix it there).
(Also did a minor bit of cleanup, renaming
ClosureTypetoContractModeand movingsplit_for_remembersto the shared module since it has contract-specific logic.)Resolves #3326
