https://crrev.com/c/3297708 changed the serialization format for typed arrays without bumping the format version. As a consequence, builds that include that CL fail to deserialize typed arrays serialized by previous V8 versions. This CL reverts the serialization format change, and does minimal test changes to reflect the revert. https://crbug.com/v8/12532 tracks serializing typed array flags in a backwards-compatible manner.

In the C++20 a following paper was implemented [1]. This paper makes code below illformed. The high level idea is that as soon as class gets non default constructor - all default initializations are not added implicitly. class A { public: A(const A&) = delete; }; int main() { A a{}; return 0; } So if V8 embedder is building its code with C++20 it can not initialize v8::CppHeapCreateParams struct and as a result can not create a CppHeap. One of the possible mitigations (3.3) from the paper is to add non copyable field into class. Luckily there is std::vector<std::unique_ptr>> in this class already.

The V8InspectorSessionImpl constructor accepts a state, as either text or CBOR encoded, and generally ignores all invalid inputs, except for the case where it's a valid value, but not a dictionary value, in which case it'll leak the value and crash upon casting to a `DictionaryValue`. This is purely an issue with the test driver, so no security impact on Chromium in the wild.

Previously, guard regions were created by allocating pages with PROT_NONE and relying on an allocation hint. This could fail however, for example on Fuchsia (where it would allocate a VMO to back the guard region) and possibly on Windows (where a placeholder mapping was replaced by a "real" mapping). Introducing an explicit VirtualAddressSpace::AllocateGuardRegion routine now makes this operation more efficient and effectively guarantees that it cannot fail if used correctly: in a regular subspace, there is no need to allocate anything when creating guard regions since the address space reservation backing the subspace is guaranteed to be inaccessible when no pages are allocated in it.

This change fixes the implementation of the previously introduced API `Runtime.setMaxCallStackSizeToCapture` to work correctly and also apply (consistently) to stack traces captured by V8 when exceptions are thrown. It does so in a fully backwards compatible manner. This change thus makes the previous fix for catapult (which landed in http://crrev.com/c/3347789) effective, and therefore ensures that real world performance benchmarks aren't affected by the use of the `Runtime` domain in the catapult test framework. Note this is basically a reland of crrev.com/c/3361839, but without touching the stack traces for console messages (which led to the regressions in crbug/1283516, crbug/1283523, etc.).

We unify the implementation of element segment expression entries with other initializer expressions: we represent them with a {WireBytesRef} and decode them with {InitExprInterface}. Except for reducing code duplication, this also fixes a bug where {global.get} entries in element segments could reference invalid globals. Changes: - Change {WasmElemSegment::Entry} to a union of a {WireBytesRef} initializer expression and a {uint32_t} function index. - In module-decoder, change parsing of expression entries to use {consume_init_expr}. Add type checking to {consume_element_func_index}, to complement type checking happening in {consume_init_expr}. - In module-instantiate.cc: - Move instantiation of indirect tables before loading of element segments. This way, when we call {UpdateDispatchTables} in {SetTableEntry}, the indirect table for the current table will also be updated. - Consolidate table entry instantiation into {SetTableEntry}, which handles lazily instantiated functions, or dispatches to {WasmTableObject::Set}. - Rename {InitializeIndirectFunctionTables} to {InitializeNonDefaultableTables}. - Change {InitializeNonDefaultableTables} and {LoadElemSegmentImpl} to use {EvaluateInitExpression}. - Add a test to exclude mutable/non-imported globals from the element section. - Update tests as needed. - Update .js module emission in wasm-fuzzer-common.

The mid-tier register allocator already did some consistency checks; this CL extends them, and removes a redundant check. The added check ensures that no two virtual registers are assigned to the same register. A separate check for the correctness of the {allocated_registers_bits_} bitset is folded into {CheckConsistency}. A second check that an allocated register is contained in {allocated_registers_bits_} is removed.

This fixes an unbalanced return stack that was caused by popping the return address and jumping to it, instead of pushing it back and returning properly.

See related CL for context. Changes: - In InitExprInterface, add the ability to evaluate function references as index only. Remove the global buffers and use the ones passed with the instance object instead. - In WasmElemSegment, add a field indicating if elements should be parsed as expressions or indices. Change module-decoder.cc to reflect this change. - In module-instantiate, change the signatures of LoadElemSegment, LoadElemSegmentImpl, and EvaluateInitExpr. Move the latter out of InstanceBuilder.
