Nathan Shively-Sanders 8ae7c6c227 Fix type predicate index in error reporting
Previously type predicate error checking didn't take the `this`
parameter into account when checking for errors. This led to spurious
errors. Note that it's not feasible to change the initial value of
`parameterIndex` because several checks refer to the original
declaration, for example to make sure that a type predicate doesn't
refer to a rest parameter.
