      [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.

      [cleanup][torque] Use @generateCppClass in some simple cases, part 2 · a5811358
      Seth Brenith authored 
      This patch is mostly mechanical. A few changes in
implementation-visitor.cc might be worth mentioning:
- Don't generate both field offset macros and class definitions for the
  same class. This was mostly just to keep me from forgetting to remove
  the DEFINE_FIELD_OFFSET_CONSTANTS part when converting classes, but
  also helpfully flagged that FixedArrayBase wasn't using the generated
  class that it requested.
- Generate forward declarations for all tq-defined classes in
  internal-class-definitions-tq.h. This is helpful for making things
  compile when classes have fields of other class types.
- When generating accessors for union types, use the nearest class type
  that contains the entire union rather than plain Object. This is
  important for compile-time type safety. It also required a few minor
  fixes elsewhere (isolate.cc, modules.cc, scope-info.cc,
  source-text-module.cc, and a correction of the field types in
  CallHandlerInfo to match how they're set in api.cc).
