hausner@google.com 4258c115b4 Handle load errors in deferred code 
IO errors on the URL of a deferred library are forwarded to the Future
that handles the deferred load. Syntax errors and finalization errors
are lethal, killing the isolate.

koda@google.com 50bb605a6a Handle-like interface for HashTable. 
A combination of two independent interface changes:
1. Constructor takes a RawArray* and allocates its own Array handle.
2. Release provides access to the entire handle, rather than just the raw.

This results in a very clean usage pattern, like:
  FooTable table(get_foo_table());
  table.Insert(obj);
  ...
  set_foo_table(table.Release());

Having the isolate inside HashTable also allows faster allocation of temporary handles.

johnmccutchan@google.com 2e59674838 Initial backend for metrics in Observatory. 
Two types of metrics:

* Counter - a measured value
* Gauge - A measured value with a min and max

Follow up CLs for the backend:

* Support for internal VM metrics (implemented in C++ but visible over the service).

Follow up CLs for the frontend:

* Query list of metrics
* Get latest value of a metric
* Collect values over time and graph them.

I'd like some feedback on the API and the data reported.
