srdjan@google.com 1125846660 When checking against non-parametrized types use a cache to hold result tuples (class, result). That cache is stored in the instruction stream. Currently implemented for instanceof, ia32 only. Should migrate to other type tests and architectures. 
70x improvement on a benchmark (similar to what is seen in html _unwrap).

hausner@google.com 6d9abc5e3b StepOver, StepInto, StepOut 
Implement single stepping in the debugger.
- Add PC descriptors for function return
- functions to set temporary breakpoints on all
  locations in a function.
- patching/restoring of function return code pattern
- determine call target of instance calls

kmillikin@google.com 41e77a0a9e Initial implementation of a flow-graph builder for Dart's AST. 
Visit the AST and generate an instruction (ie, not basic-block) flow
graph.

The flow graph for the simple function:

main() {
  var f = 1;
  var n = 5;
  while (n > 0) {
    f = f * n;
    n = n - 1;
  }
  print(f);
}

is:

       1: StoreLocal(f, #1)
       2: StoreLocal(n, #5)
       3: [join]
       4: t0 <-LoadLocal(n)
       5: t0 <-InstanceCall(>, t0, #0)
       6: if t0 goto(7, 15)
       7: [target]
       8: t0 <-LoadLocal(f)
       9: t1 <-LoadLocal(n)
      10: t0 <-InstanceCall(*, t0, t1)
      11: StoreLocal(f, t0)
      12: t0 <-LoadLocal(n)
      13: t0 <-InstanceCall(-, t0, #1)
      14: StoreLocal(n, t0) goto 3
      15: [target]
      16: t0 <-LoadLocal(f)
      17: StaticCall(print, t0)
      18: return #null

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).

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.
