closes 2462. better implicit error messages.
@implicitNotFound(msg="Custom error message that may refer to type parameters ${T} and ${U}")
trait Constraint[T, U]
whenever an implicit argument of type Constraint[A, B] cannot be found,
the custom error message will be used, where the type arguments are
interpolated in the obvious way
note: if the msg in the annotation references non-existing type params,
a warning is emitted
the patch also cleans up annotation argument retrieval (moved it to
AnnotationInfo from Symbol)
