This fixes an old bug uncovered by
https://chromium-review.googlesource.com/591651
The bug is a race between the concurrent sweeper clearing slots and
the mutator adding slots and trimming fixed array:
1) The sweeper starts sweeping a page with an existing fixed array.
2) The sweeper pre-caches the slots clearing mode by checking if the
slot set pointer on the page is null or not. (This is the bug).
3) The mutator updates the fixed array such that new slots are added.
4) The mutator trims the fixed array such that the added slots are
now in free space.
5) The sweeper adds the trimmed part of the fixed array to free list,
but does not clear slots there because of the cached flag.
6) A new object is allocated from the free list entry and it has
a bogus slot entry recorded.

- Previous fix is https://chromium-review.googlesource.com/c/583531 but it
diverges Scopes created by PreParser from Scopes created by Parser.
- This CL creates the inner block scope a bit earlier and (temporarily) pushes
it into the scope chain for parsing the variable declarations in a for
loop. The previous approach was to first parse the variable declarations and
then reparent the AST nodes / Scopes created while parsing it afterwards.
- This CL partially reverts https://chromium-review.googlesource.com/c/583531;
the new fix only touches parser-base.h (diff between patch sets 2 and 3 is the
fix).
- The Ignition golden changes are basically undoing the changes done in that CL
too.

This CL consolidates ownership of parameters used to compile code (which
we always specialize) in 2 places:
- ModuleEnv for compile-time data
- WasmCompiledModule for runtime data
The parameters in question are: memory size and start; globals start;
address of indirect function tables (and their signatures, respectively);
and address to be used for wasm call sites.
Ideally, we'd collapse this down to one place, however, we need
specialization data to survive serialization. We can achieve this we get off
the GC heap and use a different wasm code serializer.
The CL:
- removes aliasing of parts of the specialization data, and moves
to using ModuleEnv as a token of passing around compile-time data, instead
of a mixture of ModuleEnv, WasmInstance, and some other structures. ModuleEnv
is responsible for providing a consistent view of the specialization data,
e.g. valid memory sizes (multiples of page size), and matching sized function
tables and signatures.
- removes WasmInstance, as its data is now contained by ModuleEnv.
- removes ModuleBytesEnv. We now pass the wire bytes explicitly. They can't
always be assumed as present (e.g. streaming compilation), and probably more
refactoring may need to happen once streaming compilation lands and we
better understand our dependencies.

A spec change (a0dfeba1a8) introduced a number of Await operations to the spec. In turn, this caused generated bytecode for async generators to grow drastically.
This commit moves the Await within AsyncGeneratorYield (https://tc39.github.io/proposal-async-iteration/#sec-asyncgeneratoryield step 5) into a new TFJ builtin, similar in structure to AsyncGeneratorAwait, but instead of resuming the generator on resolution of the Promise, the current generator request's Promise is fulfilled instead.
This results in a reduction in generated bytecode without losing any statically available information.

Change the CALL_IC machinery inside of Ignition to collect new.target
feedback for Construct and ConstructWithSpread bytecodes instead of
collecting feedback about the target, and adapt TurboFan's JSCallReducer
to consume feedback for new.target instead of target on JSConstruct
nodes.
This enables TurboFan to inline JSCreate - and thus the actual instance
allocation - into derived leaf constructors even if the leaf constructor
itself is not inlined, and thereby removes this weird performance cliff.
The feedback for target in case of class constructors is provided by
the function context specialization, and in case of `new A`, we can
just use the feedback for new.target, as both target and new.target are
A in that case.

This is part of the effort to consolidate the ownership of
wasm instantiation/specialization parameters.
This change is focused solely on the interpreter part of that effort, to
verify we're not regressing performance in interpreter benchmarks.
There are two aspects being addressed:
- dataflow-wise, we always fetch the interpreter's memory view from the
runtime objects (i.e. WasmInstanceObject/WasmCompiledModule). This is
consistent with how other instance-specific information is obtained
(e.g. code, indirect functions).
- representation-wise, we do not reuse ModuleEnv/WasmInstance just for
the memory view, because it is surprising that other instance info isn't
accessed from there.

Refactors CompileUnoptimizedCode to do all the finalization for both
inner and the outermost function after having prepared and executed their
compile jobs. This will enable the function to be split into an off-thread
phase and a finalization main thread phase.

Moves creation of the CompilationInfo for unoptimized compilation into the
respective CompilationJobs for Igntition, Fullcode and asm.js. This unifies
the behaviour with respect to the optimized compilation jobs, and enables the
CompileInfo to be owned by the CompilationJob.
As part of this change, we no longer build new dummy ParseInfos for eager inner
functions, instead using just the single outer ParseInfo created during the
actual parsing.
