With the smi-corrupting decompression approach we don't have to sign extend Smis anymore and therefore we can switch to zero extending approach by moving the isolate root to the beginning of the reserved 4Gb region.

Just mechanical conversion to remove boilerplate code. When .tq and .h files didn't agree on what a field is named, I used the name from the .h file. In a couple of cases the generated accessor became slightly more specific (HeapObject instead of Object), and I had to update the code that uses those accessors accordingly.

TypedSlotSet is only recorded for code pages. Code pages are not swept concurrently to the application, so pre-freeing is not needed for typed slot sets anymore. Also replaces the manually allocated buffer with a regular std::vector.

Some of the methods in {WasmCodeAllocator} can be called either without holding the lock, or while already holding it. In order to support both situations, we used a {RecursiveMutex} so far. This CL refactors this to be a simple {Mutex} again, and passes a {WasmCodeAllocator::OptionalLock} object which stores whether the lock is already held or not. Note that getting the lock twice fails immediately in debug builds, while forgetting to get the lock might only fail on TSan. The alternative would be to duplicate all methods, having one variant that expects that the lock is held and one that assume that it's unlocked. It would be multiple methods though to duplicate across both {NativeModule} and {WasmCodeAllocator}, hence I went for the {OptionalLock} instead.

This CL changes the Tagged stores when pointer compression is enabled. It shouldn't affect anything for the time being since if we have pointer compression enabled, we are going to be storing Compressed values. Later, we will eliminate the Compressed representation and that it's where it will come into effect. The Arm64 side of the CL looks bigger since we eliminated the opcode in https://chromium-review.googlesource.com/c/v8/v8/+/1803345.

This CL fixes the overlap check by using {<=} instead of {<}. This allows us to always use {std::copy_n}, which should fall back to {memcpy} internally (instead of the potentially slower {memmove} we were using before). This might also fix the regressions seen mostly on atom CPUs.

The {GetNearRuntimeStubEntry} and {GetNearCallTargetForFunction} functions need to find the code space that contains the current function. This lookup requires a lock and is non-trivial. The repeated lookup caused severe regressions. This CL introduces a {JumpTablesRef} struct which holds information about the jump tables to use. It can be looked up once and then used for a whole function or even several functions within the same code space (in {NativeModule::AddCompiledCode} which adds a whole vector of compilation results). This fixes the regressions.

Placing these tests in anonymous namespaces, is the suggested fix according to the GCC documentation. The GCC documentation states: "If a type A depends on a type B with no or internal linkage, defining it in multiple translation units would be an ODR violation because the meaning of B is different in each translation unit. If A only appears in a single translation unit, the best way to silence the warning is to give it internal linkage by putting it in an anonymous namespace as well."

This CL removes the StoreBuffer and inserts slots into the RememberedSet directly from within the RecordWrite builtin. Only calls into C code when either the SlotSet-array or the bucket is not allocated. This avoids filling the store buffer up with duplicates or due to a write-heavy workload and then blocking the main thread on store buffer processing. The first CL (https://crrev.com/c/1815241) got reverted, because mksnapshot was using a different size for SlotSet than the final binary on ARM. This is fixed now, SlotSet has a standard layout.

This adds a fake toolchain for pointer compression, used for correctness fuzzing. The toolchain enables us to have an extra build with inverse pointer-compression defaults side-by-side. The extra build is used similarly to existing x64/x86 comparisons, except that we now compare builds with different compile-time flags.
