never worked reliably. This CL removes

b) the distinction between soft and hard address space limit,
c) methods to check whether memory has guard regions (it will always
have them on 64 bit architectures),
d) associated runtime functions,
e) the trap handler fallback tests,

We have very few tests for this currently, and it's hard to test
this, since code logging happens soon after scheduling the task and
stack guard. If the timing is just right, it can happen though that a
{NativeModule} dies while {WasmCode} objects of that {NativeModule} are
still part of the {code_to_log} vector. In that case, we need to remove
those code objects from the vector to avoid use after free.

The bulk memory proposal changed behavior of segment initialization
during instantiation. Previously, all segments would be bounds-checked,
after which the segments would be initialized.
The bulk memory proposal removes the up-front check, and always
initializes active segments in order, starting with element segments and
then continuing with data segments. Each active segment is initialized
as-if they were being initialized with the `memory.init` and
`table.init` instructions, so an out-of-bounds initialization may still
modify the memory or table partially.

The Torque compiler makes heavy use of scoped globals (contextuals).
This created a problem for the design of the compiler interface:
- Either the compiler provides all the necessary scopes itself,
disallowing callers any access to the contextuals, which might
contain data the caller is interested in (such as the
compilation result).
- Or the caller provides all the necessary scopes.
This design was fine when the compiler executable was the only user.
With the recent addition of unit tests and the language server, this
interface became brittle, as missing scopes are only detected at
runtime.
This CL refactors the compiler interface to not leak contextual
scopes past the interface boundary. Content of contextuals is
collected and returned, providing access for the caller and freedom
to either use the data directly or move it into the callers own scopes.

When a stack trace is captured, it is stored in a private symbol on
the respective Error object. The first access to "Error.stack" will
then format the stack trace, with a possible call into user JS via
the Error.prepareStackTrace callback.
Until now, the accessor converted ".stack" to a normal data
property containing the formatted stack trace. This causes a new Map
with a new DescriptorArray to be created, which will not be shared
with anything else (also not other error objects with formated
stack traces).
This CL changes the accessor to store the formatted stack trace in
the same symbol (stack_trace_symbol) as the structured data. The
result is that an error object will have the same Map before and
after "Error.stack" is accessed.

After this CL, MicrotasksScope allows null MicrotaskQueue parameter,
so that the user can migrate one-by-one from the default microtask
queue to the finer grained one.

Previously when an unresolved private name is not found
in the current scope but found in an outer class scope,
we forget to push it to the outer class scope so the
name would never get bound.
This patch simplifies ClassScope::ResolvePrivateNamesPartially()
and removes the search in outer class scopes since they are incomplete
at this point. Instead just push any private name that can't be
resolved in the current scope to the outer class scope so that it
gets handled later when the outer class scope is complete.

Blink used to use v8::MicrotasksScope::GetCurrentDepth() to get the
number of nested MicrotasksScope for the default microtask queue.
However, there was no corresponding one for non-default queues.
