af6a35c860 [runtime] Check for proper stack checks
When calling the {Isolate::StackOverflow} method, we should not have
overflown the stack limit by too much. Otherwise there might not be
enough space on the stack for handling the stack overflow exception.

This DCHECK would have failed before landing https://crrev.com/c/3059074
and https://crrev.com/c/3059075. If it fails, we might need to add more
special stack checks also in other places. Such failures should not be
considered security issues per se, but we should try to fix them to
avoid potential issues.

9e0e2c150c [liftoff] Add code comments for large stack checks
This adds a code comment before the OOL code for the special stack check
for a large frame. Otherwise it is hard to see where it begins in the
code, and it might be unexpected to see that block of code at the end of
a Liftoff function.

Drive-by: Replace another "out of line: " comment by "OOL: ", which is
typically understood equally well.

Rename "exception" to "tag" throughout the codebase for consistency with

72b0756ea1 [liftoff][ia32] Add explicit stack check for large frames
Add an explicit check for the available stack space before allocating a
large frame. Even though this typically does not cause problems on ia32,
we should do it to be consistent with other platforms and with TurboFan
code.

This follows the same structure as on x64: https://crrev.com/c/3059074

A follow-up CL will add a DCHECK to verify that we never overflow the
stack space by more than 4KB (https://crrev.com/c/3059076).

bce81d6be0 [wasm] Support partial serialization of modules
At the moment a WebAssembly module can be serialized successfully when
all functions were compiled with TurboFan. However, for some functions
it may not be necessary to be compiled with TurboFan, e.g. for functions
where Liftoff code is as good as TurboFan code.

With this CL we allow WebAssembly modules to get serialized even when
not all functions are compiled with TurboFan. Missing functions are
marked as missing in the serlialization. Upon deserialization, missing
functions either get compiled by Liftoff, or initialized with a
lazy-compilation stub, depending on the V8 configuration.

acb0263c7f cppgc: Fix flaky crash due to used bytes counters mismatch
Cppgc reports used bytes statistics to CppHeap. CppHeap should forward
the stats to v8. However, if we are not allowed to trigger a GC, CppHeap
will cache the stats until the reporting.
On GC finalization, CppHeap resets v8's counters to the current marked
bytes counter.
If the last reported stats before GC finalization are cached, CppHeap
doesn't clear the cache on GC finalization. On the next stats reporting,
CppHeap will report the cached values. If the cache is a decrease that
is larger than the current marked bytes, a DCHECK in
LocalEmbedderHeapTracer::DecreaseAllocatedSize will fail.

b4e62f2d14 [sparkplug] Fix invalid stack on baseline install
InterpreterOnStackReplacement_ToBaseline spills the accumulator register
without a frame, but can then call kInstallBaselineCode. If that
function then allocates, then the GC will see an invalid stack.

Fix this by making sure that the accumulator register is spilled inside
the internal frame of the kInstallBaselineCode, and either don't spill
it at all outside that frame, or at least make sure that we pop/re-push
the spilled value so that it moves inside the frame.

89cf666e14 [test] Lower the stack size & iterations on JSON test
The test makes sure that JSON parsing doesn't stack overflow if given a
deeply nested JSON object. This deep nesting makes the test slow, so we
can test ~the same thing by lowering both the nesting and the stack
size.

b971ab3067 [traphandler] Fix test link errors on some MSan/ASan builds
Found these when compiling the arm64 simulator for MSan (Release) and
ASan (Debug and Release). Depending on the exact configuration (and
compiler), different functions will get inlined and different symbols
need to be available at link time.

1) Since GetRecoveredTrapCount is used in a unittest, it needs to be
   exported.

2) The thread-local g_thread_in_wasm_code cannot be exported on
   Windows, hence it cannot (safely) be used in unit tests. Use the
   {GetThreadInWasmThreadLocalAddress} function instead, which will
   return the address of that thread-local variable.

6a77c34699 [turbofan] Move OSR entry stack check before exception ranges
The OSR entry stack check is needed as a function entry stack check to
make sure the call isn't overflowing, but emitting it as part of the
loop peeling meant that it would be within any exception handler ranges
that the loop is in.

In particular, this meant that code like this:

    try {
      loop {
          OSR();
      }
    } catch {}

would logically insert the entry stack check inside the try, and thus
stack overflows of the function call would be caught within the
function, and the function could continue runnning in an overflown
state.
