      This will enable proper reporting of OOM errors during snapshot
deserialization, for example https://crbug.com/614440#c27.

      [wasm][fuzzer] Restructure and fix bugs in wasm-compile · 318719a1
      Manos Koukoutos authored 
      Changes:
- GenerateInitExpr should emit a function reference to a function that
  is known to exist when funcref is expected.
- Add functions by signature index to the WasmModuleBuilder, so we avoid
  signature canonicalization, which currently does not work for wasm-gc.
- Remove printing of recursive groups in the WasmModuleBuilder. Instead,
  restrict type definitions to only refer to previous types.
- Some local restructuring of code, comments.

      [debug] Handle instrumentation breakpoints separate from regular breaks · b88c5a8d
      Kim-Anh Tran authored 
      This changes the way how we are handling instrumentation breakpoints.

Motivation:
with instrumentation breakpoints, we need a way to break
on (conditional) breakpoints that were just set by the client on
the instrumentation pause.

How:
We want to first find out if we have an instrumentation break, and
trigger a pause. For this to work, we need to distinguish between
regular and instrumentation breakpoints in the debugger back-end.

On resume, we want to check if we have hit any breakpoints (may
now contain new breakpoints due to the client setting new breakpoints
at the previous instrumentation pause) and trigger a separate pause
for them.

Fixed: chromium:1292930

      Revert "[runtime] Refactor TransitionsAccessor" · 7c602011
      Deepti Gandluri authored 
      This reverts commit c927ada7.

Reason for revert: GC stress failures: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux%20-%20gc%20stress/37276/overview

Original change's description:
> [runtime] Refactor TransitionsAccessor
>
> Problems:
> - The class uses a bare Map field, but some methods can trigger GC
> causing it to have a potential dangling pointer in case of map
> compaction.
> - Some methods invalidate the object state and should not be used again.
> - Complicate logic with a no_gc and a gc aware constructors. Some
> methods can only be called if the object is constructed with a
> particular constructor (e.g, Insert and PutPrototypeTransition).
>
> Note: Most usages of this class is done by constructing an object and
> calling a single method:
> `TransitionAccessor(...).Method(...)`
> So we can easily change them to a static method.
>
> This CL:
> 1. Adds DISALLOW_GARBAGE_COLLECTION to the class.
> 2. Makes methods that can trigger GC static.
> 3. Creates static helper functions that wrap the class in a different
> scope, since TransitionsAccessor now forces the scope to disallow gc.
> 4. Removes now unnecessary "Reload" logic.

So we can easily change them to a static method.

This CL:
1. Adds DISALLOW_GARBAGE_COLLECTION to the class.
2. Makes methods that can trigger GC static.
3. Creates static helper functions that wrap the class in a different
scope, since TransitionsAccessor now forces the scope to disallow gc.
4. Removes now unnecessary "Reload" logic.
