srdjan@google.com ac8041f15d First step toward deoptimization using deoptimization info: splits deoptimization into two steps: copy frame to buffer, fill unoptimized frame from buffer. The only changes in the frame are the return address and the PC marker. 
Second step will add deoptimization info 'instructions' that will fill the unoptimized frames using the saved registers and frame data.

vegorov@google.com c9e8d9594e Add support for fixed parameters in the register allocator. 
This remove bailout for functions with non-zero number of non-fixed parameters and increases our coverage.

SpillSlot location was renamed into StackSlot location and now allows to address spill slots (positive stack index) and incoming parameters (negative stack index).

Environment was reordered to match order of values on the stack (previously it was inversed).

Correctly reserve spill slots in the prologue of the code. Previously register allocator was allocating spill slots, but generated code did not reserve any space for them on the stack so they might have been overwritten by calls.

Fix off by one in DeoptimizationStub::GenerateCode - we were reserving one slot too many.

Change --optimization-filter flag to use substring search instead of prefix comparison, this is much more useful when VM prefixes function name with a path to the file.

Add debugger functionality to pause the VM whenever a TypeError

This is a first step towards breaking on handled and unhanded
exceptions in general. We first need to generate more debug info
for catch handlers so we can determine whether an exception will
be handled or not before we unwind the stack to run the catch
clauses.

turnidge@google.com 9d72035ce5 Use the ThreadPool for all isolates and native ports. Previously, 
each isolate or native port had a dedicated thread.

Refactored the MessageHandler api...

- Added a Run function to allow a MessageHandler to run on a
  ThreadPool.  These functions take a start and end callback to allow for
  isolate initialization and shutdown.

- Made the queue private to the MessageHandler and moved all message
  processing code inside the MessageHandler (got rid of all of the
  different flavors of RunLoop).  This helps remove some code
  duplication and hides the details of how messages are handled.

- Moved all locking and notification out of MessageQueue and moved it
  up to MessageHandler.  Moved OOB support out of MessageQueue and up
  to MessageHandler.  These changes make the MessageQueue much
  simpler.

- Refactored native port and isolate MessageHandlers to share more code.

- Improved --trace_isolates output.

- Added tests for MessageHandler.

Refactored lib/isolate code...

- Use the new MessageHandler::Run api.

- Got rid of the LongJump stuff in RunIsolate.  No longer needed.

- Use the new StartIsolateScope/SwitchIsolateScope to make the code
  less verbose and less error-prone.

- Store top-level isolate errors in the sticky_error.

Added StartIsolateScope/SwitchIsolateScope classes.

asiva@google.com 2d3775a1b1 Resubmit change 6302 after fixing the compiler warning on older GCC compiler versions: 
Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.
