This adds a new operator JSCreatePromise, which currently allocates
a native JSPromise instance and initializes it to pending state.
In addition to that we introduce a new PromiseHookProtector, which
get's invalidated the first time someone enables the debugger or
installs a PromiseHook (via async_hooks for example). As long as
the protector is intact we lower AsyncFunctionPromiseCreate to
JSCreatePromise and AsyncFunctionPromiseRelease to a no-op in
optimized code.
This yields a speedup of roughly 33% on the benchmark mentioned
in the bug.

FixedArrays hanging off recursively of the constant pool without any
real objects in between can be considered as meta data. They are shared
with optimized code (embedder pointers).

This adds a tri-state flag --infra-staging and --no-infra-staging, which
can be used to explicitly opt in or out of the staging test runner.
If not specified, a new architecture whitelist will enable roll-out per
arch for manual (none CI) runs.
We'll start whitelisting archs in follow ups.

Since we're not winning anything by changing the result between
processors on the main process, reduce is noop there and result is
