In assignments the lhs should be evaluated first and shouldn't be
re-evaluated when the value of the rhs is available. Fix it by
saving the receiver and the key registers into AssignmentLhsData
before building the assignment and use them later, instead of visiting
the AST again to retrieve the receiver.

In addition, now that we save the receiver register, use it to
perform the brand check even when we know for sure that it's
going to fail later because it's a write to a private
method or accessing the accessor in the wrong way (v8:11364),
so that the brand check error always appears first if it is present,
as specified in
https://tc39.es/proposal-private-methods/#sec-privatefieldget

Drive-by: unify the brand check error messages, and replace "Object"
with "Receiver" in the messages for clarity. The instance private
brand check now throws "Receiver must be an instance of class <name>"
and the static private brand check now throws "Receiver must be
class <name>". Also always set the expression position to the
property load position, because the brand check failure comes from
the load operation.

In the future we will allow arbitrary objects as host-defined options.
To prepare the embedders for the upcoming changes we migrate the API
to use v8::Data where possible.

Internally we still use i::FixedArray with primitive values until the
migration to context-stored host-defined options is completed.

Note: This CL also introduces a temporary cast and inheritance
between Data and PrimitiveArray which will be removed again.

In order to construct the optimal source code combination for functions
(and especially the positions inside the optimal source code for each
function), we need to know all functions upfront.

Rewrite the d8-based snapshotter so that it discovers all objects first
(+ assigns ids), then does the actual snapshotting.

Adds support for aborting compaction when finalizing with stack:
- never_compact_with_stack: All pages are aborted;
- never_compact_code_space_with_stack: Only code space pages are
  aborted;

This flags allow simulating a worst case where a stack cannot
be considered precise, or evacuation candiate is refered to from
a stack slot that V8 has no info for.

This CL fixes a memory leak where we would not properly pop all
Promises from the Isolate-wide Promise stack. This can happen under
the following conditions:
  - `await`ing a Promise in an async function
  - Debugger is active
  - AsyncEventDelegate is not set.

In the case above, the promise of the surrounding async function is
pushed onto the global Promise stack, but not poped before the
await. This CL fixes that.

This CL
* adds forwarding accessors to CodeDataContainer for certain widely
  used Code object's fields and predicates,
* adds JSFunction::set_code() overloads accepting CodeT values,
* migrates SharedFunctionInfo getters to CodeT,
* migrates InterpreterData::interpreter_trampoline to CodeT.

Drive-by-fix: replace #if V8_EXTERNAL_CODE_SPACE with #ifdef to be
consistent.
