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.

which is not resolved until an unhandled exception occurs.  If a callback
wasn't specified, the VM will then call an "_unhandledExceptionCallback"
function if it is defined in the isolate's source file. If no callback
is provided, the error is logged as the isolate is closed.

This CL adds AND, OR, XOR and == operations on unboxed 64-bit integers

Unboxed mints are stored in xmm registers. Each xmm register location
has an additional bit to keep track of its value representation.

Unboxed mints are materialized on the heap on deoptmization in the same way as
unboxed doubles.

The SSE instructions used are available on all CPUs that support SSE 4.1.

turnidge@google.com bd995a345e Avoid trusting the length encoded in the Snapshot if there is an 
external length available.  We now pass a length with all messages in
the vm and verify that there is no mismatch with the length from the
Snapshot.

Fixed a bug in the use of ApiMessageReader.  We were always manually
adding Snapshot::kHeaderSize to the data, but neglecting to subtract
kHeaderSize from the message length.

Added FullSnapshotWriter and MessageWriter classes.
