Certain collators and subject strings may take this new fast
path without calling into the (slow) ICU comparison functions.
This CL can be roughly split into three topics:
1. The fast path check, precomputed and implemented as a whitelist
on the current locale string.
2. The actual fast path, which checks subject string eligibility
and performs L1 and L3 collation weight comparisons all in one pass.
3. Resuming from an aborted fast-path into the generic path.

JetStream2/cdjs scores improve by roughly 40%.

The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.
With this change, mjsunit tests pass on x64.
The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.
Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.
