asiva@google.com 109cbae3dd Minor cleanup of activation frame creation code. Get the code object while iterating the frames as that is way faster than doing a code lookup later.

asiva@google.com f4fe42c280 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^=")

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.

- Send isolate events over to the debugger client in the following format:

===>  "{" event ":" isolate "," params ":" "{" reason ":" shutdown "," id ":" Integer "}" "}"
===>  "{" event ":" paused "," params ":" "{" reason ":" interrupted "," callFrames ":" StackTrace "}" "}"

- Added id ";" Integer, to params in all paused events messages

- create per isolate debugger message queues, instead of the global static one

- Add 'i' command in ddbg to exercise the interrupt feature

- Add support for handling isolave event messages in ddbg

asiva@google.com 5cbd276939 Make the parser agnostic to the TokenStream implementation. This is the first step towards compacting the token stream. 
Pull the data stream writer/reader code out of snapshot into a generic file so that it can be reused into the token stream compaction implementation.

hausner@google.com 7d00d4b2e6 Do not collect stack trace unnecessarily 
The debugger collected stack traces on each exception throw
even when the debugger client specifies "no pause on exception".
This fixes the asserts that Anton saw in some tests.
