Do not count invocations but usage of a function, i.e., increment a function's counter at IC calls and at return operations in unoptimized code. (TODO: increment count at static calls as well). There is no checking at method entry any more. The function counter reporting is not measuring the invocation count but much more how much time we spend in a method. Removed counter at backward branches.
...
Renamed flags to:
--optimization_counter_threshold (default 2000)
--report_usage_count

Add support for interrupting an isolate in the vm. Interrupts are
...
implemented by extending the existing support for stack overflow
checking in the vm. When an interrupt is scheduled for an isolate, we
overwrite the isolate's stack limit with a value guaranteed to cause a
stack overflow.
We support multiple kinds of interrupts, encoded in the low bits of
the stack limit.
Add Dart_InterruptIsolate and Dart_InterruptIsolateCallback to the
dart embedding api to allow the embedder to request and handle
interrupts.
Add EXPECT_SUBSTRING(needle, haystack) testing macro.
