Ryan Macnak df64bb1619 - Annotate instructions that load objects from the ObjectPool or Thread. 
- Remove disassembly tooltips.
- Surface whether a function has an intrinsic or is recognized.
- Mark intrinsified or ffi functions in the profile.

Florian Schneider b5966db69e VM: Clean up and fix bugs in instructions patterns 
Fix bug in DecodeLoadWordFromPool: used Array::element_offset instead of ObjectPool::element_offset.
This only worked because they accidentally return the same value.

Remove virtual methods from InstructionsPatterns on ia32 and x64. Instead use a template for code reuse.
This avoids among others vtables for the *Pattern classes and saves >= 4K in VM binary code size.

John McCutchan baa34257fc Track prologue offset of Code and use for more precise return addresses 
- Remember the prologue offset in the Code object.
- Size of Code object does not change.
- Use the prologue offset to assist in locating the return address of the current frame.
- Prologue offset + instruction pattern matching will be accurate for all Dart code, most intrinsic prefixed Dart code, and some stub code.
- By default only collect Dart frames (normal Dart developers only care about Dart frames)

johnmccutchan@google.com f2333f63a5 Add Function based profile tree 
Profiler improvements:
- Track Functions in profile and build Function based trie
- Associate code objects with functions
- Created cpu_profile.dart library
- Major speed improvements for disassembly view
- Fix truncation of disassembly comments
- Ability to get code object ticks from disassembly view
- Inlining mini-map in disassembly view.
- Remove a bunch of unused data from profile service response
- In some cases a caller PC that is better than the PC marker is inserted into the stack trace
- Inlined functions are expanded
- Ability to clear profile
- New flag '--keep_code' which keeps deoptimized code around for use by the profiler.

General fixes:
- Fix caching in service library
- Remove pubspec.yaml before running pub get

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
