This patch adds infrastructure for collecting feedback about call_ref call targets in Liftoff code, and using that feedback for turning such calls into inlineable direct calls when building Turbofan graphs. The feature is considered experimental quality and hence off by default, --wasm-speculative-inlining turns it on.

Currently, when compiling with V8_VIRTUAL_MEMORY_CAGE enabled, the behavior of the BoundedPageAllocator changes from simply making freed pages inaccessible to decommitting them, which guarantees that they will be zero-initialized after the next allocation. As this seems to cause some performance regressions on Mac, this CL introduces a new enum that specifies how the allocator should behave: kAllocatedPagesMustBeZeroInitialized causes the pages to be decommitted during FreePages() and ReleasePages() and thus guarantees zero-initialization during AllocPages(). kAllocatedPagesCanBeUninitialized only causes the pages to be made inaccessible, and so does not generally guarantee zero-initialization for AllocPages(). Finally, this CL also removes some dead code in allocation.cc.

Certain collators and subject strings may take this new fast path without calling into the (slow) ICU comparison functions. This CL can be roughly split into three topics: 1. The fast path check, precomputed and implemented as a whitelist on the current locale string. 2. The actual fast path, which checks subject string eligibility and performs L1 and L3 collation weight comparisons all in one pass. 3. Resuming from an aborted fast-path into the generic path. A longer overview is available at https://docs.google.com/document/d/1oyDwjYn2JyHsx2YnJJKhjX0WMNQXb8ao86-DRzqiYNg/edit?usp=sharing JetStream2/cdjs scores improve by roughly 40%.

The current implementation of the default ArrayBufferAllocator for the virtual memory cage is highly inefficient as it simply forwards all requests to the cage's PageAllocator. With this CL, this allocator is now only used when the heap sandbox is enabled, in which case ArrayBuffer backing stores must be located inside the cage. In all other cases, in particular when only the virtual memory cage is enabled, the backing stores can be located outside the cage and so the malloc-based ArrayBufferAllocator is used. This change only affects configurations in which V8's default ArrayBufferAllocator is used.

WebAssembly dynamic tiering should be tested with an origin trial. For the origin trial the feature flag value has to be loaded from blink. This CL stores the value of the --wasm-dynamic-tiering flag in the compilation state, from where it gets passed forward to all uses of the flag. The flag value gets loaded from blink when a new NativeModule is created.

With dynamic tiering, typically not all functions of a WebAssembly module get compiled with TurboFan, and therefore the code caching would never get triggered. With this CL code caching is triggered whenever {FLAG_wasm_caching_threshold} bytes of TurboFan code are generated. This new caching event is only triggered when --wasm-dynamic-tiering is enabled.
