vegorov@google.com a77fc9701c When requested to extract a method M from class C inject a method extractor (consisting of a single AST node CreateClosure) as a getter get:M into C. 
This allows to cache and optimize method extraction requests as normal method invocations and at hot method extraction sites that significantly decreases overhead of method extraction which previously required two trips into runtime system and was not cached at all.

asiva@google.com fff63865e6 Add a new operator |= which does a simple assignment of the raw pointer into 
a handle without any vtable settings. In debug mode there are the usual checks
to ensure that the vtable in the handle matches the expected vtable value
based on the dynamic type of the object.

It is useful in loopy code as follows:
  const Array& funcs = class.functions();
  Function func = Function::Handle();
  for (int i = 0; i < 100000000; i++) {
    func |= funcs.At(i);
  }

fschneider@google.com 75c4844bf5 Cleanup uses of X::CheckedHandle where X::Cast or X::Handle is sufficient. 
The only places where CheckedHandle is appropiate is with arguments to
runtime functions and values from Dart API functions.

For other places in the VM either normal Handle and ^=, or Cast is sufficient.

T::Cast is used when the value is guaranteed to be of type T (and never Object::null()).
Otherwise, the operator^= is used for casting.

Also fix a style issue where a Raw* should be used as return type.

asiva@google.com a76bd61fcb When externalizing a string ensure that the basic tag bits are preserved. 
Also make sure we do not try to externalize read only strings that are in
the VM isolate.

asiva@google.com b7673910ab Fix for issue 6359 - Make snapshots platform independent. 
The issue previously was that an instance size was stored a
size in bytes, similarly field offsets were stored as an offset
in bytes. This caused issues when generating the snapshot on
one platform and reading it on another platform.
The VM has been changed to store the instance size as a size in
words and the field offset as an offset in words.
