Instead, this CL wraps sync*'s sync_op in an additional function
that captures local copies of the necessary closure state.
Notably this state includes the parameters of the original sync* function
as these also need to be cloned for each instance.


Note: a large number of .expect files have a small number of changes

* Allow some mixed mode stuff: Eventually the SDK should be in agnostic

Anna Gringauze 9f65693f57 Use offset for detecting scope in ExpressionCompiler 
ExpressionCompiler currently translates offsets of scopes to line
numbers during the binary search in the library in order to find
the inner-most scope containing the line where debugger has stopped.
This results in many offset-to-line translations per evaluation request,
each translation also performing a binary search in Source.lineStarts
table.

To make scope lookup more efficient, this change uses Source.lineStarts
table to find the offset for the debugger stop once, and uses integer
offset comparisons instead in the scope binary search.

Martin Kustermann c4a7c3488e [vm/async] Make async transformer use typed variables, make async patch use function types 
This gets rid of a slow AssertAssignable (function type test)
in _asyncThenWrapperHelper/_awaitHelper, which currently falls back to the slow table
search:

  AssertAssignable

          ^--> SlowTypeTestStub

Johnni Winther 0a9e57419b [kernel] Make verbose qualified names conditional in toStringInternal 
Including the library name/uri in types and member names makes these
unreadable in most cases. This changes that default toStringInternal
to omit the library name/uri but supports a verbose mode that includes
the library name/uri for debugging the rare occasions where they matter.

This is a bare-bones implementation (and test) for having an explicit
toString on all `Node`s.
This can then be extended as-needed to better suit our debugging
purposes. It's not allowed to leak, though.

Clement Skau b681bfd8d2 [VM] Fixes bad reuse/typing of temps in async transform invocations. 
For a method invocation temps might get allocated for both the receiver
and argument(s) so that:
  A().foo(await null)
becomes:
  Future<void> tmp0
  ...
  tmp0 = A() // <- Type mismatch.
  yield ...
  tmp0 = tmp0.foo(:result) // <- Correct type.

This happens because the liveness analysis finds that the (previously
dynamic) temps can be reused.
Unfortunately 121988 added typing information to these temps, which
means they can't be simply reused in all cases.

This fix makes the temps dynamic again (by removing the type) but adds
unsafecasts to all VariableGets to propagate the know type.
