Seth Brenith 91e6421ccb [torque] Use generated instance types, part 1 
This change begins making use of the fact that Torque now knows about
the relationship between classes and instance types, to replace a few
repetitive lists:

- Instance type checkers (single and range), defined in
  src/objects/instance-type.h
- Verification dispatch in src/diagnostics/objects-debug.cc
- Printer dispatch in src/diagnostics/objects-printer.cc
- Postmortem object type detection in
  tools/debug_helper/get-object-properties.cc

Torque is updated to generate four macro lists for the instance types,
representing all of the classes separated in two dimensions: classes
that correspond to a single instance type versus those that have a
range, and classes that are fully defined in Torque (with fields and
methods inside '{}') versus those that are only declared. The latter
distinction is useful because fully-defined classes are guaranteed to
correspond to real C++ classes, whereas only-declared classes are not.

A few other changes were required to make the lists above work:

- Renamed IsFiller to IsFreeSpaceOrFiller to better reflect what it does
  and avoid conflicts with the new macro-generated IsFiller method. This
  is the part I'm most worried about: I think the new name is an
  improvement for clarity and consistency, but I could imagine someone
  typing IsFiller out of habit and introducing a bug. If we'd prefer to
  keep the name IsFiller, my other idea is to rename FreeSpace to
  VariableSizeFiller and Filler to FixedSizeFiller.
- Made Tuple3 extend from Struct, not Tuple2, because IsTuple2 is
  expected to check for only TUPLE2_TYPE and not include TUPLE3_TYPE.
- Normalized the dispatched behavior for BigIntBase and HeapNumber.
- Added a few new object printers.
