26e02eea57 MIPS: Add tool to visualize machine code/lithium. 
Port r17295 (b36eb655)

Original commit message:
In the process:
- Add a command-line flag --opt-code-positions to track source position information throughout optimized code.
- Add a subclass of the hydrogen graph builder to ensure that the source position is properly set on the graph builder for all generated hydrogen code.
- Overhaul handling of source positions in hydrogen to ensure they are passed through to generated code consistently and in most cases transparently.

66bb9d1563 Record allocation stack traces 
This is initial implementation of allocation profiler.

Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.

Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.

19b2ee1c40 Handlify PropertyCell::SetValueInferType and friends. 
This finally gets rid of the pesky trampoline in SetValueInferType and
enforces the layering between PropertyCell and Heap. It requires full
handlification of NewGlobalObject as well, which is only used when the
snapshot is created at compile-time.

b8dd056fa2 Improve queuing for concurrent OSR. 
Specifically, this includes:
- Encapsulating data structure for osr buffer into CyclicBuffer
- Use the new CyclicQueue instead of UnboundedQueue to queue new jobs.
  We can enqueue and dequeue a CyclicQueue on both ends in O(1).
  This allows us to add OSR jobs to the front for lower compile latency.
- Dispose osr buffer by one stale job per GC to avoid leak
