Improve Syb code (#621)
Specialize.hs and Ast.hs are modified to have their Syb code not recurse into
Name or Id in HsSyn types.
Specialize.hs is refactored to have fewer calls to Syb functions.
Syb.hs has some foldl calls replaced with foldl' calls.
There is still a lot of performance on the floor of Ast.hs. The RenamedSource
is traversed many times, and lookupBySpan is very inefficient. everywhereBut and
lookupBySpan dominate the runtime whenever --hyperlinked-source is passed.
