kmillikin@google.com c70bcfcfa3 Support constant folding of instructions with constant smi values. 
In sparse conditional constant propagation, replace instructions with

jackpal@google.com 3e510176c2 Fix Android build breaks 
Prevent Android's STLPort from undefining global functions from
math.h when cmath is included after math.h.

The Android STLPort does not provide std::assert or std::atexit. Use
the C versions of these functions on Android.

turnidge@google.com ec36e02c28 Remove the partially completed code for remote IsolateMirrors and 
replace it with the beginnings of a local (same isolate) IsolateMirror
implementation.

Removed old mirror tests and added two new mirror tests.

Even though mirrors.cc is part of the vm, I chose to implement most of
it using the dart embedding interface instead of our internal
interfaces because the embedding interface was more convenient.
mirrors.cc is basically all new in this CL -- don't pay any attention
to diffs for that file.

Added dart embedding functions required for the functionality in this
CL: Dart_DebugName, Dart_GetNativeInstanceFieldCount,
Dart_RootLibrary, Dart_RegisteredLibraryUrls, and Dart_LibraryName.

Extended or modified some existing dart api functions, primarily to
make them propagate error handles properly.

Added tests for new dart embedding api functionality.

Added the ability to determine if a port is local to the current isolate.

Extended NotImplementedException to accept an optional string
argument.  I wanted to give more descriptive error messages.

hausner@google.com 95be46105a Beginnings of a debugger wire protocol 
The debugger wire handler is implemented similarly to the io event handler.
A dedicated thread monitors the debugger port for incoming connection
requests. When a debugger is connected, the VM sends events messages
over the wire and handles debugger requests.

To start the VM with a debugger connection, use the option
--debug:<portnumber>. The VM pauses at the beginning of main()
and waits for a debugger to connect.

Subsequent changes will implement debugger commands one by one.
With this change, the VM only understands "resume" commands.

ager@google.com e92d0eab5a Reimplement Windows Monitors. 
Now using an event object per thread which is linked into a list
of waiters for the monitor.

Notify takes the first element of the list and notifies (FIFO order).

Notify all extracts the entire list and notifies each of them. This
avoids the issues with fairness and correctness of the previous version.

The MonitorWaitData object holding the event and a pointer to the
next waiter is stored in thread local storage and lazily initialized.

sgjesse@google.com 3f035ecad0 Add support for lists and backward references when decoding a message to a Dart_CObject object 
The C message reader can now read lists created like this:

  new List()
  new List<int>()
  new List<String>()
  new List<double>()
  new List<bool>()

The backward references are now resolved and already allocated
Dart_CObject objects are reused when there is a backward reference.

The reuse of the Dart_CObject objects poses the issue of which objects
where allocated with the supplied allocator and which where not.

Currently this will work best with a zone allocator. This will be added
to the tests in a subsequent change.

interface for running all threads in the VM.

sgjesse@google.com c1d041500f Use hash map for event handler file descriptor map 
Instead of using an array indexed using the file descriptor for
looking up data associated with a socket (SocketData objects) this is
now stored in a hash map using the file descriptor as key.

Added hash map implementation like the one used in the V8 project.
