fschneider@google.com 937726a0aa Improve polymorphic inlining of int/int double/double operations. 
I added inlining of the native Double methods _add, _sub, _mul and _div and fromInteger
and unified the method recognition of the MethodRecognizer and the Intrinsifier classes.

johnmccutchan@google.com e7ddd5d047 Move some isolate state setup from C++ code to JumpToExceptionHandler stub (take 3). 
- CL is the same as take 2, but, I now prohibit the profiler from walking the call stack when the isolate is executing the jump to exception handler.

Isolate::Current() when using these accessors.

asiva@google.com 09adb99a85 Add a stub_code_space in the heap alongside code_space so that stub code generation happens here and it is easy to determine if a PC is a stub code or not. 
This gets rid of the temporary change made in code_generator.cc for fast access to the top dart frame. In addition it will not pollute the pc ==> code cache that I plan to add next as we don't have to store stub pcs in that table.

asiva@google.com 3107319e40 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.

sgjesse@google.com bf67f24098 Move assert.h/assert.cc from runtime/vm to runtime/platform 
The purpose of this change is twofold:

1. Source in the bin directory can now use the same assertions as
   source in the vm directory. The ASSERT macro used by the code
   in runtime/bin was just defined to use assert from the standard
   C library.
2. Moving other implementation parts from runtime/vm to
   runtime/platform (e.g. classes Monitor and Mutex) for sharing
   between runtime/bin and runtime/vm will be easier as these
   implementations rely on these assertion macros.

Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.

All the code for asserts is still in the dart namespace.

Also re-arranged the order of includes to be alphabetically in
the files touched.
