asiva@google.com 17c7958b33 Some minor cleanup.

regis@google.com cb6c1b27f3 Implement checked mode in new compiler. 
The only remaining bailout is the boolean type check for conditions.

regis@google.com 5282e44fb2 Use null type argument vector instead of vector of Dynamic for a generic raw 
type when possible.
Fix type finalization of type parameters (always finalize in the context of the
class being parameterized and not in the enclosing class where the type
parameter is used).
Fix wrong generic optimization and added a test (a generic type instantiated
from a raw instantiator is not always raw).
Added printing of type argument vectors.

Implement single stepping in the debugger.
- Add PC descriptors for function return
- functions to set temporary breakpoints on all
  locations in a function.

srdjan@google.com a343a49338 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

srdjan@google.com a54f33bf92 ICData is now a wrapper object that refers to the calling function, target name, ic data array, etc. The old ICData C++ class that wrapped around an Array is removed. The advantage is that the ICData object remains the same, only its ic_data array object is being modified as classes are added.. 
TODO: store ICData-s into function so that the type feedback can be easily extracted (currently must traverse the unoptimized code).

turnidge@google.com 0b833d4977 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.

- object is canonical

compressed into a single header word.

hausner@google.com b7cf1328a1 Very first steps for a debugger 
- Introduce Debugger class.
- Each isolate has a debugger object.
- Introduce stubs that can be put in place of static or dynamic
  Dart function calls.
- Very rudimentary command line option to place a breakpoint
  at the beginning of a function.
