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.

Bug: https://github.com/flutter/flutter/issues/51828
