  - Dart_ClassGetTypedefReferent
  - Dart_ClassIsFunctionClass
  - Dart_ClassGetFunctionClassSignature
  - Dart_FunctionReturnType
  - Dart_FunctionParameterType

Other stuff:

- Fixed bug in Function::NumberOfImplicitParameters for signature
  functions.

- Chnaged the default upper bound for type variables to Object from
  Dynamic.  Discussed this with Gilad and Regis.

- Fixed some smaller problems in mirrors_impl.dart.

lrn@google.com 292da5cc48 Make int an abstract class. 
This looks deceptively simple (the only real change is in init, which
just copies the code for double, and the rest are just renaming for
consistency). It seems to work.

asiva@google.com 724b8600d4 Move all the closure related fields in RawFunction into a new class 
called RawClosureData
Add a field called 'data_' in RawFunction which points to a RawClosureData
object for closure functions, a signature class for signature functions or
an implicit closure function if there is an implicit closure for a regular
function.

This ensures that we don't burn 5 fields in RawFunction for normal functions.
The heap savings from this change on standalone dart is about 67k.

After this change:
New space (0k of 32768k) Old space (886k of 1024k) Code space (0k of 0k)

Prior to this change:

in order to save space in function objects.
