Scopes in V8 are used to guarantee one or more properties during its lifetimes. If a scope is not named e.g MyClassScope(args) instead of MyClassScope scope(args) it will get created and automatically destroyed and therefore, being useless as a scope. This CL would produce a compiling warning when that happens to ward off this developer error. Follow-up to ccrev.com/2552415 in which it was introduced and implemented for Guard classes.

Apple's upcoming arm64 devices will prevent rwx access to memory, but in turn provide a new per-thread way to switch between write and execute permissions. This patch puts that system to use for the WebAssembly subsystem. The approach relies on CodeSpaceWriteScope objects for now. That isn't optimal for background threads (which could stay in "write" mode permanently instead of toggling), but its simplicity makes it a good first step.
