Jordan DeLong 9584995bec Fix (disable) reporting of extended typehints via reflection 
Right now (on trunk, not release), a function with a ?int
typehint tells the reflection API its typehint is just "int".  For
now, just turn this off.  (If we want this later we'll probably have
to add a new API or something?)
