When using the tip of TL with some local changes, the behavior I'm 
seeing is that declaration annotations on type parameters are *not* 
being retrieved from the AnnotedConstruct methods when called on a 
TypeParameterElement. I wanted to double check if this was the expected 
behavior right now or if I should continue to look for operator error on 
my part. (I see there are some langtools tests which reference 
TYPE_PARAMETER, but I haven't traced through what they test.)
