johnmccutchan@google.com 919dc2d6eb * Introduce ThreadInterrupter which calls a TLS set callback when thread is interrupted. 
* Threads can only register and unregister themselves with ThreadInterrupter.
* Profiler is no longer involved in interrupting threads. It's just a callback and the buffer.
* Profiler operates lock free using an atomic operation to reserve sample in sample buffer.
* Linux, Mac, and Windows done.

iposva@google.com 070d3dedf7 - Add a per-isolate pseudo random number generator to the 
VM internals. This PRNG is not used to generate random
  numbers in Dart code.
- Use the PRNG to generate JIT cookies for large constants
  if needed during assembly.
- Add the possibility to set an external entropy source
  for the PRNG through the C API.

asiva@google.com 1cd2ad79ec Fix for 12312 (Dartium crash when reloading after running tests). 
Add framework for Dart_Cleanup which will cleanup stuff on exit.
Ideally the VM isolate should be shutdown in Dart_Terminate but we don't
seem to have a clean thread pool shutdown as a result of which there are
racing isolates.

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.

cshapiro@google.com 0928c651e5 Implement a 2-pass heap verification algorithm. 
The previous algorithm would visit each pointer in the heap and verify it
without regard for whether the pointer had already been visited.

The new algorithm computes the set of allocated objects and verifies each
object in the set.  In a second pass, each pointer is visited and tested
for membership in the set.

BUG=2606
