* Fix second bug in Trac #4127
This bug concerned the awkward shadowing we do for
Template Haskell declaration brackets. Lots of
comments in

* Fix Trac #4127 (and hence #4173)
The change involves a little refactoring, so that the default
method Ids are brought into scope earlier, before the value
declarations are compiled. (Since a value decl may contain
an instance decl in a quote.)
See Note [Default method Ids and Template Haskell] in
TcTyClsDcls.
