Enforce "joined()" and "joined_with_noop()" test

Several similar tests come in the form of `joined()` and `joined_with_noop()`. In this test, the `joined()` has two calls to a noop, making it functionally equivalent to `joined_with_noop()`. This doesn't seem intended, and this PR removes those calls and changes the memory size to reflect the change

For my education, why do tests with `noop()` calls sometimes have `noop()` contributing to the size, while others do not? E.g. https://github.com/rust-lang/rust/blob/master/src/test/ui/async-await/async-fn-size-moved-locals.rs#L115 and https://github.com/rust-lang/rust/blob/master/src/test/ui/async-await/async-fn-size-moved-locals.rs#L116 have no size difference, whereas https://github.com/rust-lang/rust/blob/master/src/test/ui/async-await/async-fn-size-moved-locals.rs#L113 and https://github.com/rust-lang/rust/blob/master/src/test/ui/async-await/async-fn-size-moved-locals.rs#L114 have a size difference. Thank you!
