mtklein@google.com bd6343b1d6 Rewrite SkTRegistry to take any trivially-copyable type.
Obviously these are all currently function pointers of type T(*)(P) for various
T and P.  In bench refactoring, I'm trying to register a function pointer of
type T(*)(), which can't be done as is (passing P=void doesn't work).  This
also lets us register things like primitives, which is conceivable useful.
