Thread/Isolate refactoring: new(Isolate*) -> new(Zone*)
...
Refactor all remaning cases where the current zone is used through new(Isolate*) and remove this interface.
Removing this interface is needed to move towards multiple threads per isolate, and also makes the caller more aware of the scope of the zone used, reducing the risk of use-after-free.
Make the current thread and the stack zone created around native/runtime entries directly available in their body, saving an indirection (and optimized away if unused).

Replace scalarlist optimizations and split external array loads into two IL instructions.
...
This CL removes optimized access for scalarlist, and only the new TypedData classes
are optimized. I changed the runtime libraries core and math to use typedData
instead of scalarlist (Uint16List is used in StringBuffer, Uint32List by Math.random).
Instead of using LoadIndexed for internal and external arrays,
split external loads into a load of the backing store and a load
of the element.
v3 <- LoadIndexed(v1, index)
becomes
v2 <- LoadUntagged(v1, ExternalTypedData::data_offset)
v3 <- LoadIndexed(v2, index);
For this I introduce two new representations in the IL:
kUntagged (for values that hold a untagged pointer) and
kNoRepresentation (for instructions accept any input
representation)
Deoptimization does not need to know about kUntagged
since these values can never occur in the environment.
Also with this change:
* fix COMPILE_ASSERT and use it in one place.
* Cleanup IL printer output of deopt ids.
