The stack offsets of cache slots are always positive, but the compiler does not know that. The lack of this knowledge makes division by the system pointer size significantly more expensive. One solution would be to rewrite the division to be an actual right shift. Another solution is to teach the compiler that offsets are positive. This CL does the latter. This reduces the overall Liftoff compile time of the reproducer in the linked issue by nearly 25%.

For prototype loads from strings, we require an access check, since string maps are shared between native contexts. This makes our prototype constant load optimisation bail out to a generic load. We can, however skip this check given the knowledge that this is a prototype load from a primitive, and instead emit a string check. We can also be a slight bit more tolerant of multiple different string maps, same as TF.

As sandboxed pointers are now default-enabled when the sandbox is enabled, it is no longer possible to deactivate the sandbox at runtime. This CL therefore removes all the logic that was required to support a sandbox that could be disabled at runtime, moves the initialization of the sandbox into V8::Initialize, and deprecates V8::InitializeSandbox. This change also makes the sandbox initialization deterministic if FLAG_random_seed is supplied.
