asiva@google.com 4b2c10ae32 Added following dart API changes to enable more efficient access based 
on the dartium usage pattern:
- Dart_GetNativeStringArgument (gets a String object, peer etc. directly from
  the native arguments)
- Dart_SetWeakHandleReturnValue (allows a weak handle to be passed to the
  return value, this ensures a new local handle does not have to be created
  from a weak handle just to return a value)
- Dart_StringGetProperties (gets some common properties of a string, avoids
  multiple API calls to set up a native string)

vegorov@google.com 2565ca222f Implement a variation of scalar replacement for non-escaping allocations. 
AllocationSinking pass discovers non-escaping allocations that have no input uses other than uses in the stores into its own fields.

Every environment use of such allocation is replaced by a state snapshot (MaterializeObject instruction) that describes the state of each initialized field in the object. State snapshots are computed through an additional round of load-forwarding.

Once snapshots are computed allocations are removed from the graph.

MaterializeObject instructions are not compiled into native code but produce deoptimization instructions instead that describe how object should be materialized at deoptimization.

Deoptimization instructions now follow the following format:

[mat obj #1]...[mat obj #N][ret addr][... mat arguments ...][... real frames ...]

- the prefix describes each object to materialize on deopt via kMaterializeObject instruction;
- actual values that are needed for materialization are emited as a part of bottom-most stack frame. This is done to simplify implementation: they need to be discoverable by a GC during materialization phase. At the end of deoptimization they will be removed from the stack;
- normal stack slots can refer to materialized objects via kMaterializedObjectRef instruction.

Additionally this change contains fixes in load-forwarding that are needed to guarantee that all artificial LoadField instructions inserted during AllocationSinking are correctly replaced with actual values.

Limitations of the current implementation:

- can't eliminate allocations that flow into phis but otherwise don't actually escape;
- can't sink allocations out of loops;
- allocation with type arguments are not handled.

asiva@google.com 27e78fb6f8 Second step towards loading core library scripts directly from the sources 
- Modify the library source generator to generate a source mapping array
  The generated array is of the following format:
  const char* dart::Bootstrap::corelib_source_paths_[] = {
    "dart:core", "/workspace1/dart-all/dart/sdk/lib/core/core.dart", 

    "bool.dart", "/workspace1/dart-all/dart/sdk/lib/core/bool.dart", 
    ...
    ...
  };

- Read the source file using the source mapping array instead of relying on
  a generated buffer containing the sources

- Modify the gyp files to ensure that all libraries are read directly
  from the sources. This CL does not change the patch part yet.
  Remove the source concatentation step in the gypi files for all the core
  libraries.

ager@google.com 6e945a2578 Optimize the message queue for many active ports with few messages. 
The current message queue implementation is very inefficient if you are using
many active ports with few messages. This happens when you use 'call' a lot
on ports which is currently done in dart:io.

This patch does not remove messages from the queue when closing a port. Instead
it drops messages for closed ports when it processes them. This dramatically
speeds up dart:io benchmarks that enqueue tons of writes on a file output
stream.
