  Fix 19210: Poor error message for `return` function parameter that is not
`ref`

  If the type does not have references, adding `return` won't help.
  This we only suggest adding `return` when it actually has an effect.
  In addition, value types parameter are now qualified of "local variable",
  because that's what they are.
  Last, when the error is on `this`, the message advise to annotate the
function.
