We see too many regressions for now in M94 (~10% more misses in some cases). This CL reverts the logic to the state before landing https://crrev.com/c/3069152 without having to revert the several refactoring CLs that landed on top of it.

The heap sandbox will rely on the virtual memory cage to protect the data pointers in ArrayBuffers, TypedArrays, and DataViews.

This introduces a new, optional `nonIndexedPropertiesOnly` flag to the `Runtime.getProperties` inspector request, which tells the inspector to only report properties whose name is not an (typed) array index. This is to support retrieving all properties except for the indexed ones when the DevTools front-end decides to use the array bucketing mechanism. Previously the DevTools front-end had some quite complicated logic in place to simulate this via injected JavaScript, but that logic didn't pick up internal properties and was also interfering with the inherited accessor mechanism. With this new flag, it's straight-forward to implement the correct behavior in the DevTools front-end. The corresponding devtools-frontend CL is https://crrev.com/c/3099011.

In follow-up work, the parser will be refactored to take the input as raw char arrays instead of a FlatStringReader s.t. it can be reused by the V8 parser (which has AstRawStrings instead of Strings).

The optimal implementation is in TurboFan x64 codegen, move it into shared-macro-assembler, and have TurboFan ia32 and Liftoff use it. The optimal implementation accounts for AVX2 support. We add a couple of AVX2 instruction to ia32 in sse-instr.h, not all of them are used, but follow-up patches will use them, so we add support (including diassembly and test) in this change. Drive-by clean up to test-disasm-x64.cc to merge 2 AVX2 test sections.

The old implementation had an implicit assumption that IsolateData::builtin_entry_table_offset is a uint12, i.e. <4096. We're about to cross that threshold, so this patch frees up a temp register to let the code generator handle larger offsets.

{NativeModule::AddCode} is a central method that should usually be called in batches, where the caller holds a {CodeSpaceWriteScope} for a longer time (over several compilations). This CL moves us closer to that by removing the scope from that central method and instead putting it in callers where it becomes more visible. There are already TODOs to introduce caching or batching to avoid some switching, and one more TODO is added. Drive-by: Remove an unneeded {CodeSpaceMemoryModificationScope}.

This ensures that we have enough slack to land or merge important fixes (and temporarily coming closer to the limit).
