Selected first UserCtorsAndDefaultOfHack clause in resolvePrimInit().
Removed PRIM_INIT conditional in resolvePrimInit() and adjusted indentation.
Moved FLAG_TUPLE clause from generateConcreteConstructorCall() to resolvePrimInit().
Resolution of PRIM_INIT on tuples always resolves to _defaultOf(), since it is expected to be compiler-generated.
Update .good files changed due to explicit use of ChapelNumLocales in LocaleModel files.
Simplify a few constructor names.

Replace astr() calls with a direct reference to the name from another source.
