Specialization action.

The crickets at http://www.scala-lang.org/node/11901 were in
unanimous agreement that I should proceed as suggested.

 - No arguments to @specialize gets you 10/10, not 9/10
 - Fixed bugs in AnyRef specialization revealed by trying to use it
 - Specialized Function1 on AnyRef.
 - Changed AnyRef specialization to use OBJECT_TAG, not TVAR_TAG.
 - Deprecated SpecializableCompanion in favor of Specializable,
   which has the virtue of being public so it can be referenced
   from outside the library.
 - Cooked up mechanism to group specializable types so we don't
   have to repeat ourselves quite so much, and create a few groups
   for illustrative purposes.  I'm not too serious about those names
   but I used up all my name-thinking-up brain for the day.
 - Updated genprod and friends since I had to regenerate Function1.
 - Put tests for a bunch of remaining specialization bugs in pending.

Closes SI-4740, SI-4770, SI-5267.
