We should only check the "SIMD sibling" register if we are handling a SIMD register. This avoids unneeded spills, and in this particular case ran into a DCHECK because there are only 29 registers, but we tried checking #29.

This is a reland of be6bd4f4. The reason for revert was two bots timing out. On further inspection, the timeouts seem unrelated.

Inlining the field accesses make the code simpler by avoiding the abstraction of the accessor, and makes stepping through the code for debugging easier.

Since the accessors are only called from other methods in the same class, we can just access the field directly. This makes stepping through easier and makes the code simpler by avoiding an unneeded abstraction.

The register state is accessed a lot in the mid-tier register allocator. Instead of going through an accessor with a DCHECK, just access directly. This makes stepping for debugging a lot easier, and will result in an easy-to-debug nullptr access if the register state is not initialized.

Spilling was already fixed if a fixed SIMD register overlaps with an allocated FP register, but the other way around was missing: If an odd FP register (in this case d1) is used as a fixed output register, but this register is in use as the upper half of a SIMD register (in this case q0), we did not detect this and would just use overwrite the SIMD half. This CL also fixes this case.

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.

Aleksei Koziatinskii authored
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.

Clang 12 doesn't support -Wno-bitwise-instead-of-logical, so silence it with -Wno-unknown-warning-option. GCC requires using GNU dialect of the C++ standard, using optimizations (otherwise "always_inline" fails to inline), and produces a lot of warnings that had to be silenced. Signed-off-by:
