Summary of changes:

- GC visitors no longer rely on superclass visitors, but instead visit
  everything themselves. This enables generating better code.
- Try to match simple body descriptors to reduce the amount of generated
  code.
- Turn SizeFor(instance) into an AllocatedSize() method.
- Remove the special handling of resizable object sizes from Torque
  and instead overwrite AllocatedSize in classes that need special
  handling in C++.
- Split the visitor id lists depending on whether the class has pointer
  fields.
- Turn Torque-generated body descriptors into an .inc file to
  simplify includes.
- Fix generated size functions to properly align the size.
- Generate GC visitors (and C++ class definitions) for all string
  classes and FixedArray, WeakFixedArray, and WeakArrayList.
- Store generated instance types in Torque class types. This is only
  used to determine if a type has a single instance type in this CL.

Motivation:
Improve code efficiency by replacing runtime calls with manually written
turbofan code where possible.

Changes:
- Remove the runtime functions `Runtime_WasmExceptionGetTag` and
  `Runtime_WasmExceptionGetValues` and replace them with turbofan code.
- Introduce the builtin function `GetOwnProperty`.
- Change `wasm-compiler.h` and `wasm-compiler.cc` to accomodate the new
  changes.
  - Introduce three new macros in `wasm-compiler.cc`.
  - Use those macros in two additional places to remove code
    duplication.

Any function with heap-allocated variables starts by creating and
pushing a new context for its execution. When entering the debugger due
to the stack check in the beginning of InterpreterEntryTrampoline, the
function has not yet had a chance to push that new context. The code in
ScopeIterator currently assumes that any function which needs a context
already has one by the time the debugger attempts to iterate scopes, but
in this case that assumption is invalid, which can cause a null deref.

This change introduces a new function ScopeIterator::NeedsAndHasContext
to replace previous calls to current_scope_->NeedsContext(). This new
function checks for the case where the current scope matches the closure
scope but the context matches the containing context for the function,
which implies that the function has not yet pushed its own context.

Torque desugars try-catch/label constructs with several handlers
into nested try structures, with the first handler ending-up
innermost. So currently, if you write

try {
...
} label Foo {
  Throw(...);
} catch (e) {

}

The catch will catch the preceding Throw in another handler.
This is different from how multiple try-catch handlers are done in
languages like Java, where throwing from a preceding catch handler
is not caught by a later one. To avoid this possible ambiguity, this
CL prohibits this pattern, enforcing that a catch handler comes first,
before any other label-handler attached to the same try.
This way, a catch handler never catches from any other handler on the
same try, since they have to come later.

Original change's description:
> Reland^4 "[runtime] Amortize descriptor array growing for fast-mode prototypes"
> 
> This CL:
>  - stops tracking transitions for fast maps that are known to be detached
>  - reuses descriptor arrays when transitioning detached maps to avoid O(n^2) performance and garbage creation
> 
> Fix2 in reland: constructor_or_backpointer can be a smi since it can also hold a user-provided function.prototype
> Fix in reland: check whether the map of the back pointer is the metamap rather than reading the map of the constructor-or-backpointer slot. If the slot contains a constructor, it's possible that the object transitions while the concurrent marker is reading the map (from which it's reading the instance type); and it's possible that the transitioned map isn't set up yet fully when we read the instance type. An acquire load for the constructor-or-backpointer map would also fix it by serializing stores, but is more expensive. Checking the metamap is faster.
> 
> Original commit message:
> > This avoids an O(n^2) algorithm that creates an equal amount of garbage.
