      [cleanup] Use @generateCppClass on more classes · 334b94e1
      Seth Brenith authored 
      Most Torque-defined extern classes already use @generateCppClass. As
Nico pointed out in [1], it would be nice to convert the remaining
classes and remove this option. This change converts most of those
remaining classes. I know that the future of Torque-defined classes is a
subject of some debate right now, but I think that it's worth doing a
few mechanical changes to reduce the existing variety of options.

Changes that don't exactly follow the usual pattern:
1. BigIntBase, MutableBigInt: we can define these without a body, and
   then Torque treats them as "really external" rather than "kind of
   external, but with some Torque-generated parts".
2. RegExpMatchInfo: moved its inline functions into a separate file,
   which the generated -tq.cc file requires.

      [torque] generate C++ class definitions per Torque file · 03f60296
      Tobias Tebbi authored 
      This CL splits the class definitions per .tq file, to realize the
following relationship:
A class defined in src/objects/foo.tq has a C++ definition in
src/objects/foo.h. Torque then generates:

- torque-generated/src/objects/foo-tq.inc
  An include file (no proper header) to be included in src/objects/foo.h
  containing the Torque-generated C++ class definition.

- torque-generated/src/objects/foo-tq-inl.inc
  An include file (no proper header) to be included in
  src/objects/foo-inl.h containing inline function definitions.

- torque-generated/src/objects/foo-tq.cc
  A source file including src/objects/foo-inl.h that contains non-inline
  function definitions.

Advantages of this approach:
- Avoid big monolithic headers and preserve the work that went into
  splitting objects.h
- Moving a definition to Torque keeps everything in the same place
  from a C++ viewpoint, including a fully Torque-generated C++ class
  definition.
- The Torque-generated include files do not need to be independent
  headers, necessary includes or forward declarations can just be added
  to the headers that include them.

Drive-by changes:
A bunch of definitions and files had to be moved or created to realize
a consistent 1:1 relationship between .tq files and C++ headers.

      [torque] Generate instance types · 8c7ae314
      Seth Brenith authored 
      Design doc:
https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit

Changes from the design doc:
- Changed to use 'class' declarations rather than 'type' declarations
  for things that need instance types but whose layout is not known to
  Torque. These declarations end with a semicolon rather than having a
  full set of methods and fields surrounded by {}. If the class's name
  should not be treated as a class name in generated output (because
  it's actually a template, or doesn't exist at all), we use the
  standard 'generates' clause to declare the most appropriate C++ class.
- Removed @instanceTypeName.
- @highestInstanceType became @highestInstanceTypeWithinParentClassRange
  to indicate a semantic change: it no longer denotes the highest
  instance type globally, but only within the range of values for its
  immediate parent class. This lets us use it for Oddball, which is
  expected to be the highest primitive type.
- Added new abstract classes JSCustomElementsObject and JSSpecialObject
  to help with some range checks.
- Added @lowestInstanceTypeWithinParentClassRange so we can move the new
  classes JSCustomElementsObject and JSSpecialObject to the beginning of
  the JSObject range. This seems like the least-brittle way to establish
  ranges that also include JSProxy (and these ranges are verified with
  static assertions in instance-type.h).
- Renamed @instanceTypeValue to @apiExposedInstanceTypeValue.
- Renamed @instanceTypeFlags to @reserveBitsInInstanceType.

This change introduces the new annotations and adds the ability for
Torque to assign instance types that satisfy those annotations. Torque
now emits two new macros:
- TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the
  InstanceType enumeration
- TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String
  parts of INSTANCE_TYPE_LIST

The design document mentions a couple of other macro lists that could
easily be replaced, but I'd like to defer those to a subsequent checkin
because this one is already pretty large.
