Changed the API in DartEntry for invoking dart code from C++ to make it more compatible with the requirements of the runtime.

Deleted all the code duplication that was added to circumvent the old DartEntry API requirements.

Deoptimization can occur at Dart calls (includes native calls to C) but not at runtime calls. This assumption (verified with Todd and Gilad) simplifies the implementation of lazy deoptimization considerably.
...
Add flag --deoptimize-alot, which will lazily deoptimize all live optimized frames. Currently only the presence of deoptimization information is checked.
Add kDeoptAfter deoptimization point, which is the continuation for lazy deoptimization, after a call. Rename kDeopt to kDeoptBefore.
Removed a tests case that called into a native without properly setting up a Dart frame (Ok-d by Siva).
Native functions are not optimizable.
TODO: Split deoptimization information from DeoptimizationStubs. Check for redundant PcDescriptor information (what can be merged, especially at calls).

Properly name the first implicit parameter to factories as ':type_arguments'
(instead of 'this', which made it accessible to user code).

Remove kAbstract from the list of function kinds. It now has its own
dedicated bit. This allows us to distinguish abstract methods from
abstract getters and setters.

Simplify representation of stack frames. Remove the special types DartFrame/StubFrame and instead use StackFrame with methods IsDartFrame and IsStubFrame for frames representing Dart or Stub Code. This eliminates all the complexity that was added to ensure that we always see only one stub frame before hitting a dart frame during iteration.
...
Fixes bug 6380625 which was another case when we had two stub frames before hitting the dart frame.
