…m/array/tuple literals unless *all* sub-expressions had side effects. This would easily allow side effects to slip through, and also wrongly label empty literals as having side effects. Add some tests for the last point

Just remove a typo.

`Expr::can_have_side_effects()` is incorrect for struct/enum/array/tuple literals

It would return 'false' unless *all* sub-expressions had side effects. This would easily allow side effects to slip through, and also wrongly label empty literals as having side effects. Add some tests for the last point

The function is only used for simple lints and error messages, so not a serious bug.

Remove redundant calls to `resolve_vars_with_obligations`

I've been auditing the calls to `resolve_vars_with_obligations` for the new solver, and have found a few that have no effect on diagnostics. Let's just remove 'em.

Also remove a redundant `resolve_vars_with_obligations_and_mutate_fulfillment` call.
