It is an invariant that objects in the shared heap never point into
per-Isolate heaps. This is currently broken by DependentCode. At the
same time, shared maps and other holders of DependentCode are designed
to never invalidate optimized code. E.g., shared maps are effectively
immutable.

This CL does two things:

1. Prevent shared objects from being depended upon
2. DCHECK that shared objects never cause deoptimization

LocalHeap only uses LABs for allocation with size below
kMaxLabObjectSize. Larger allocations used a path that was unaware of
alignment restrictions.

Bring implementations of LocalHeap and regular PagedSpace closer
together by assuming the caller of their free list allocations takes
care of size and alignment adjustments.

Drive-by: Use unaligned allocations when possible which avoids a call
into PreceedWithFiller(size) which would only bail out late for
0-sized fillers.

In the case of bugs creating shared->local edges, this lets us catch
dangling pointers via CHECKs before they happen.

Also removed some redundant checks in the shared struct verifier.
Existing heap verification already checks that all of a Heap's pointers
are contained within it.

SeqStrings have their padding bytes serialized as 0s for deterministic
snapshot contents. Currently this is done by mutating the SeqStrings and
memsetting their padding bytes to 0 when serializing. This mutation is
not threadsafe in the presence of shared strings. This CL removes the
mutation by serializing the data and padding payloads separately for
SeqStrings.

With recent changes, we resolve the promise of e.g. WebAssembly.compile
with the external API, and not the V8-internal API. The external API,
however, also handles microtasks, and depending on the MicrotasksPolicy,
may also execute microtasks immediately. This means the then-handler of
WebAssembly.compile may get executed within all the scopes that were
open when the external API was called. One of the open scopes is the
CancelableTask that finishes WebAssembly compilation.

The deadlock seen in the issue arises now when {quit()} gets called in
the then-handler of WebAssembly compilation.  The reason is that
{quit()} terminates the isolate, and during isolate termination, we wait
for all running CancelableTasks to finish. This, however, means a
deadlock, because the task that terminates the isolate is waiting for
itself to finish.

SourceTextModule::ExecuteAsyncModule asserts the execution of
the module's async function to succeed without exception. However,
the problem is that TerminateExecution initiated by embedders is
breaking that assumption. The execution can be terminated with an
exception and the exception is not catchable by JavaScript.

The uncatchable exceptions during the async module evaluation need
to be raised to the embedder and not crash the process if possible.

There seems to be a bug in gcc which causes link errors after
this CL: https://crrev.com/c/3714238

Issue seems to happen when using default template argument
of function type. A related bug report on bugzilla:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105848

A workaround is to explicitly instantiate the template
for type <bool>.
