During loop exploration implemented for wasm loop unrolling, we can exit early if we already know that the loop is too large to unroll.

For adding stack checks in optimized code, we compute a conservative estimate of the frame size in the case of a deoptimization. Earlier we included the size of arguments adaptor frames used when actual arguments didn't match formal parameter count. Though we don't have an explicit adaptor frame, we should still include the size of these additional arguments when computing the frame size.

Calls >4gb may have pretty bad performance on 64bit processors that use 32bits to encode branch prediction. By passing in a function in the binary as a hint to mmap it's more likely we'll be given an address close to the binary. This may significantly improve performance on many types of 64bit cores, especially those without hyperthreading.

This CL sets it so that the actual object size is reported only when cppgc_enable_object_names is set to true. Otherwise the heap snapshot merges nodes and the sizes don't make sense. Also, this will resolve a web test failure for the library.

To improve performance of parking, keep the thread state in an atomic variable instead of protecting it with a mutex. However the mutex was used e.g. to force Unpark() to block while the safepoint operation was still running. Therefore the safepoint algorithm has to change as well. Park() and Unpark() use CAS operation to transition the state. Safepoint() uses a relaxed load for checking whether a safepoint was requested. Since Safepoint(), Park() and Unpark() all have a slow path, there is no need for busy-waiting on the main thread. We need two more ThreadStates: * SafepointRequested: This state is set by GlobalSafepoint to force Running threads into the slow path on Safepoint() and Park(). This state also replaces the separate atomic<bool> safepoint_requested_ field we used before. * ParkedSafepoint: This state is set by GlobalSafepoint as well to force parked threads into the slow path on Unpark(). When stopping all threads, GlobalSafepoint transitions states from Running --> SafepointRequested and Parked --> ParkedSafepoint to force the slow path for all three methods. After performing the transition for each thread we know the exact number of Running threads and wait until each of them either reached a safepoint or parked itself.

Optimize extadd_pairwise when AVX is supported. If SSE4_1 is available, we can use the SSE version of the same code sequence. However, there is a potentially better lowering that only requires SSE2, which has less instructions, but will only work better if we have rip-relative constants (otherwise even using ExternalReference it would be 2 moves).

This CL adds WasConservativeGC to HeapState which reports whether the last GC was finalized conservatively. The state is updated at the end of marking atomic pause. Currently the library integration in Blink ignores the stack state when scheduling a forced GC for testing. That means that we always schedule another GC after a forced GC. This causes a crash in web_tests which assume no GC is happening between forced GCs if the thread is not idle and no new allocations happen.

- cppgc_headers: Do not depend on any internals but merely expose the public API interface. - v8_libbase: Do not depend on v8_headers but merely on v8_config_headers as src/base should be independent of general V8.
