      [torque] Get rid of @generatePrint annotation · 267b067b
      Seth Brenith authored 
      I'm trying to remove annotations and make behavior more consistent. For
@generatePrint, there are two options: either generate printers for
every extern class, or never generate printers for extern classes. This
change implements the option of always generating printers. Classes that
require custom printing can easily hide the generated printer by using
DECL_PRINTER. This causes the generated file
gen/torque-generated/objects-printer.cc to grow to 1600 lines, including
many functions that are never used, but I think the consistency benefit
outweighs a little more compilation time on one file. This change also
removes custom printers in cases where the generated printer includes
all of the same content.

If folks would prefer the option to never generate printers, I'm open to
doing that instead. I like the notion that generating more code could
reduce the friction of adding new classes and thereby encourage people
to define precise types rather than using FixedArrays, but the current
implementation of generated printers is limited, and many printers have
been customized to show the data that matters the most. Unlike verifiers
and body descriptors, there are no correctness or safety concerns with
hand-written printers.

Some bugs showed up once we start generating printers for everything,
and this change fixes them:
- Printers incorrectly included ungettable fields like padding
- Printers called getters which might be hidden by hand-written classes
- The generated getter for Map::instance_type used
  ReadField<InstanceType>, which is not an arithmetic type since it's an
  enum

One more tiny drive-by fix: added a missing newline in the printers for
JSMap and JSSet.

      [torque] Remove unused field offset macros · d5625e35
      Seth Brenith authored 
      Nobody uses the generated *_FIELDS macros anymore, so we can remove
them. I also renamed the generated file to represent its content better.

      [asm] Fix importing monkey-patched objects · 4b6ee115
      Clemens Backes authored 
      This fixes a long-standing TODO to disallow importing receivers that
have "toString" or "valueOf" patched. Calling those methods could have
observable side effects, so allowing that would require bigger
refactorings to ensure that we only call each such function exactly once
per import, and in the right order.
Since this use case is rare, we just forbid importing such receivers.

      PPC/s390: Create Instance Type for Class Constructors · 7245d2c1
      Milad Fa authored 
      Port: 1cd7a582

Original Commit Message:

Class Constructors are special, because they are callable but [[Call]]
raises an exception. Instead of checking if a JS function is a class
constructor for every JS function call, this CL adds a new instance
type for class constructors.
This way we can use a fast instance type range check for the common
case, and only check for class constructors in the uncommon case were
a class constructor is called and when we need to raise an exception.
