This change makes CTX available by not caching the current

Isolate::top_context is not needed anymore since the current context

Await always waits
...
The expression ‘await e’ always suspends the enclosing function. If e does not
evaluate to a an object o of type Future, a new Future is created using Future.value(o).
A small change in the backend allows a return instruction to be followed by
other instructions. In async functions, a return can suspend the function and the
continuation point is in the same code block after the return.
Other small changes:
- More user-friendly error message if async/await is not enabled.
- Programs no longer need to import dart:async when using async/await.

Write barrier audit, part 1.

First step towards complete audit of all writes to the heap for write barrier compliance (at least on simulator debug builds).
This first CL is a semi-mechanical refactoring to route most Object field writes through StoreNonPointer and StoreSmi methods.
A few stores were converted to StorePointer (skipping the write barrier check is premature optimization for those cases).
Next step will be to make raw_ptr() return a const pointer and use the constness to clean up remaining writes in C++.
