Added macros OBJECT_IMPLEMENTATION and FINAL_OBJECT_IMPLEMENTATION
...
which have different implementations of 'operator=' and 'operator^='.
In the case of FINAL_OBJECT_IMPLEMENTATION we do not do the vtable setting
in these methods (Note the |= operator functionality is now subsumed into
the new implementation of "operator^=")

Optimize function at its entry instead of at exit.
...
The code can be patched if it should not be executed any longer.
The code can be now patched at other location than at entry, the requirement is still that patching code does not overwrite an inlined object.
Intrinsic methods that do not have a fall through cannot be patched.

Pass IC data and arguments descriptor to IC miss runtime functions.

Before, we obtained them by pattern matching backwards on the machine
instructions at the call site. This previous approach becomes unwieldy when
we need to use to use multiple instance call patterns.

When checking against non-parametrized types use a cache to hold result tuples (class, result). That cache is stored in the instruction stream. Currently implemented for instanceof, ia32 only. Should migrate to other type tests and architectures.

ICData is now a wrapper object that refers to the calling function, target name, ic data array, etc. The old ICData C++ class that wrapped around an Array is removed. The advantage is that the ICData object remains the same, only its ic_data array object is being modified as classes are added..
...
TODO: store ICData-s into function so that the type feedback can be easily extracted (currently must traverse the unoptimized code).

Dart function calls.
