fschneider@google.com 876193b31a Make CTX allocatable by the register allocator.
This change makes CTX available by not caching the current
context while in Dart code. Instead the current context
is held in a local variable (:saved_current_context_var) and
is passed as argument in CTX at calls.

This also simplifies a lot of code in the debugger: As a result,
Isolate::top_context is not needed anymore since the current context
can always be extracted from a Dart frame.

hausner@google.com 28f8a0ecae Do not notify debugger on stack overflow
Don’t call back to the debugger on out of memory and stack overflow
exceptions. The debugger can’t do anything meaningful on the VM
when the stack is full.

This should eliminate crashes we see in Dartium devtools.

This means we can no longer intercept stack overflows with the debugger.
In a later change, I plan to add uncomment the code that notifies
the debugger of the exception after the stack in unwound. Before this
notification gets uncommented, we need to make sure that debuggers
can handle notifications with an empty stack.

johnmccutchan@google.com b3f2fb14d0 Reduce CPU usage when no isolates need to be profiled (e.g. when an isolate calls readLineSync or sleep the isolate owns the thread but is blocked).
This CL does the following:

- Introduces two new API entry points: Dart_IsolateBlocked and Dart_IsolateUnblocked.
- The thread interrupter thread goes into a deep sleep if no isolates need to be profiled (not scheduled on a thread or are in a blocking call).
- When an isolate unblocks, the thread interrupter thread resumes regular interrupts.
- dart:io readLineSync and sleep mark that they are making a blocking call.

This fixes https://code.google.com/p/dart/issues/detail?id=18126 reducing CPU usage to 0% when waiting for stdin or sleeping.

hausner@google.com c6101ca4b5 First step towards asynchronous loading of sources. With this change, sources are read asynchronously in dart code (builtin.dart) and when the i/o future completes, a callback in the VM loads and compiles the script or library code.
In a next step, the i/o will be moved to the service isolate so that not all isolates have to import dart:io.

Fallout from this change:
1) Loading has become a tad slower. Will have to investigate why.

2) Errors that happen during loading (file not found, compilation error in an imported library)  are no longer reported at the offending import clause. This can be fixed later if necessary by passing the import clause source location to the library tag handler.

Details:

- Rig DbgMsgQueueList so it can run even when the debugger hasn't started.

- Add <action-link> element for pause/resume actions.

- Introduce new flex-percentile css classes.

- Add <isolate-run-state>, <isolate-location>, <isolate-shared-summary>, and <isolate-counter-chart> elements.  Counters are now displayed as a pie chart instead of as text.

- Reorg <isolate-view> and <isolate-summary> substantially.

- Add shared style sheet to <script-view>.

- Combine pause-on-start/pause-on-exit with other debugger pause events and present a consistent representation for these in the vm service.  Reorg how pause events are shown in <isolate-run-state>.

- Give the user a nicer message when an isolate is still loading.

- Move the /resume command to /debug/resume.  Implement this with a bool in the Isolate class which is used to smuggle resume requests from the vm service to the dart embedding api.

- Add the /debug/pause command to the vm service

- Break the DebuggerEvent struct out into its own top-level class.  Add JSON printing.

- Each isolate starts off with a 'Default' UserTag set.
- A null tag cannot be set.
- Calls to clearCurrentTag() should be replaced with a call to UserTag.defaultTag.makeCurrent().
- makeCurrent returns the previously current tag.

This allows for the following pattern to work:

callee() {
  var old = calleeTag.makeCurrent();
  ...
  old.makeCurrent();
}

caller() {
  var old = callerTag.makeCurrent();
  ...
  callee();
  assert(getCurrentTag() == callerTag);
  ...
  old.makeCurrent();
}

johnmccutchan@google.com ef666553a1 Add runtime and native entry tags
- Split runtime and native entry tags.
- Set runtime / native entry address as vm tag in stubs.
- Add reverse native entry resolver (pc to name) to public API (breaking change).
- Hookup reverse resolver for standalone VM (io + bootstrap + builtin natives).
- Runtime entries are registered with tags.
- Profiler queries for tag names via the reverse native entry resolver.
- Profiler outputs named entry tags as children under parent tag (runtime or native).

turnidge@google.com 1eba6be2b2 Implement new stacktrace and deoptimization stress testing flags:
--deoptimize-every=N
--deoptimize-filter=FunctionName
--stacktrace-every=N
--stacktrace-filter=FunctionName

Add a word of stack_overflow_flags to the Isolate.  Use a bit in this
word to indicate whether or not a function is being compiler for OSR.
This allows us to distinguish an OSR overflow from a stress-testing
overflow.
