    Original change's description:
    > [traphandler] Add simulator support
    >
    > This prepares the trap handler to support being used from simulators.
    > Modifications to the arm64 simulator will be done in a follow-up CL. For
    > now, the trap handler will be registered but not used in Wasm (we emit
    > explicit bounds checks instead, as before).
    >
    > The implementation uses inline assembly, so it is only available on x64
    > POSIX systems for now. This is the main platform we use for testing and
    > for fuzzing, so it should give us the test coverage we need. If needed,
    > inline assembly for other platforms can be added later.
    > The new code will be executed by the existing arm64 simulator bots, e.g.
    > "V8 Linux - arm64 - sim".
