RFR: 8042778: Getting all visible methods in ReferenceTypeImpl is slow

[Jeremy Manson]

Hi Jaroslav,

I haven't written many Streams yet, so perhaps I'm missing something
obvious / well-known.  Streams can replace the original code in an obvious
way (filter the elements of list based on whether they are contained in
map.values()), but I'm not sure how the filter operation becomes O(1)
unless we build the HashSet?
