... so that the offset fits into the maximum offset for load byte instruction for arm/arm64 (Ldrb) in order to produce smaller code. Update code generation so that the loading of the flag value is combined with the comparison operation where possible. Additionally, this CL moves the Isolate::is_profiling flag to the IsolateData so that it can be loaded directly via roots register which removes one indirection. The fields moved in the IsolateData: - is_marking_flag and is_minor_marking_flag (checked by write barriers) - is_profiling (checked on API callbacks/getter calls) - stack_is_iterable (not super hot, checked during deoptimization). Drive-by: this CL defines the bool fields as uint8_t in order to make the field size expectations clear.

We use a hash for different things: - dumping wasm module to file, - generating the script name, and - computing prefix hash / wire byte hash for caching. Two of them were using the StringHasher, one use base::hash_range. For experimental PGO support, we will also need a hash value, so unify this to use the same hash everywhere. Since the result of base::hash_range is platform-dependent, use the StringHasher everywhere.

Those are not safe in combination with the sandbox as they are stored as raw pointers. Instead of turning them into ExternalPointers (which use the ExternalPointerTable indirection), this CL simply turns them into on-heap ByteArrays which is cheaper and should be unproblematic security-wise as their contents can be corrupted without causing memory corruption outside the sandbox address space (just incorrect behaviour and/or further memory corruption *inside* the sandbox, which is fine).

Currently the ability to create shared isolates is partially exposed to API. Instead of fully exposing it, this CL makes shared isolate and shared heap handling transparent to the embedder. If a flag that requires the shared heap is true (currently --shared-string-table and --harmony-struct), the first isolate created in the process will create and attach to a process-wide shared isolate. Subsequent isolates will attach to that shared isolate. When that first isolate is deleted, the shared isolate is also deleted.

This change also modifies the way references are typed: Instead of using the static type (which may be a generic type like anyref) the actual type based on the referenced object is used. While this is very useful for arrays and structs (and somewhat nice for i31 not just being a number but also having some type information), it means for non-null values that the reference type is "not nullable", so it will show e.g. "ref $type0" although the static type might be "ref null $type0".
