Issue Description:

The following incorrectly produces errors:

type(of:)(5) // error: Missing argument label 'of:' in call

func foo(_ fn: () -> Void) {
  withoutActuallyEscaping(_:do:)(fn, { fn in }) // error: Missing argument label 'do:' in call
}

and the following incorrectly compile:

type(of:)(of: 5)

func foo(_ fn: () -> Void) {
  withoutActuallyEscaping(_:do:)(fn, do: { fn in })
}

We should be stripping the argument labels from compound references to type(of:) and withoutActuallyEscaping(_:do:), like we would for other functions.

This also appears to be the case with _openExistential(_:do:).
