Now hopefully getting it right, but still leaving in the confusing flag implications.

Runtime profiler uses bytecode array size for the tiering up decisions. Bytecode array size includes the header size as well. Inlining heuristics use bytecode array length instead. Bytecode array length is just the size of bytecode not inlcuding any headers. This change is to keep both of them in sync to avoid confusion. Also, the header contains several pointers and hence the size changes depending on the size of kPointerSize.

Use the (D)CHECK_{EQ,NE,GT,...} macros instead of (D)CHECK with an embedded comparison. This gives better error messages and also does the right comparison for signed/unsigned mismatches.

This CL refactors allocation & reservation logic into a new DefaultSerializerAllocator class. In upcoming work, this will be further extended by a custom allocator for builtin serialization.

This is primarily to aid in testing the Wasm out of bounds trap handler. We keep track of how many faults have been recovered by the Wasm trap handler. This count is exposed to JavaScript through a testing-only runtime function. This allows tests to verify whether the trap handler is actually running.

Sanitize imports before we start the instance building process. This avoids the possibility of exiting to JS while building instances, and allowing JS to observe an inconsistent state of the wasm world - e.g. incomplete specialization chains. We now validate we never exit to JS during that process.

Promises can sometimes be resolved after the RealmScope has been destroyed, such as when a Wasm compile job finishes after the script main has finished. If the Promise.then function refers to Realm.current, we were getting a use-after free error when it would search for the list of realms. This change also zeros out realm_count_ in addition to deleting the realms_ so that RealmFind will not reference freed memory.

When using Lockers and Unlockers it is possible to create a scenario where multiple threads point to the same optimized code object. When that happens, if one of the threads triggers deoptimization, then the stack replacement needs to happen in the stacks of all threads. With this CL, the deoptimizer visits all threads to do so. The CL also adds three tests where V8 used to crash due to this issue.

We'll use this allocator in a follow-up CL to: - allocate speculative sizes of memory for a module that's being compiled (e.g. 2*size of wasm code). - each module will own such a sub-pool, and then use it to allocate contiguous chunks of memory for code. The underlying assumptions for the chosen allocation strategy is that: - the allocation granularity for pools is 1 page, so that no one page is owned by more than one wasm module - typical pool sizes (given module sizes) are multiple pages. - modules and module instances are typically few and long lived. Typically, we expect one module and one instance. This means we shouldn't expect fragmentations that lead to code being non-allocatable, or prohibitively many ranges. The data structure just manages ranges of addresses. Virtual memory management will be separate, as part of the responsibility of a "WasmHeap" that will be introduced in the future. So will concurrency control.

- Moves base::VirtualMemory to v8::internal::VirtualMemory. - Makes VirtualMemory platform-independent by moving internals to new OS:: static methods, for each platform. This will make it easier to delegate memory management in VirtualMemory to V8::Platform, so that embedders like Blink can override it. We can't depend on V8::Platform in base/platform.

Fuchsia changed their kernel name from Magenta to Zircon and all the functions and defines along with it. In order to be able to roll the SDK in Chromium, we first need to land with this define added in v8, so that can roll in to Chromium, then roll the Fuchsia SDK with this magic define set (CHROMIUM_ROLLING_MAGENTA_TO_ZIRCON), then actually update v8 to reference zx_ instead of mx_ and roll that again.
