iposva@google.com 51447e92ba - Start adding meta data for fields of VM internal classes. 
- Correctly report instance size in bytes.
- At least report field sizes for variable sized objects.

hausner@google.com 7e70aaddf7 Support for embedded Dart scripts 
Add a line and column offset to scripts so that errors and exceptions
in embedded Dart scripts are reported at the proper location.
New API call Dart_LoadEmbeddedScript() that allows to specify
line and column offsets.

Stumbled on and fixed a bug. Script::kind field was not externalized to snapshot.

srdjan@google.com 04fc29c7e1 Optimize function at its entry instead of at exit. 
The code can be patched if it should not be executed any longer.
The code can be now patched at other location than at entry, the requirement is still that patching code does not overwrite an inlined object.
Intrinsic methods that do not have a fall through cannot be patched.

hausner@google.com e8a293c05a Allow optimized code when debugger is active 
The debugger allows the VM to optimize code unless there is a breakpoint inside the
function. Whenever a new breakpoint is set (explicitly or implicitly by stepping)
all optimized code is discarded.

sgjesse@google.com 7fc2230b02 Add support for surrogates when serializing and deserializing for native ports 
As Dart allows creating string with UTF-16 surrogate code units which
are not always in lead/trail pairs, we need to support this in the
communication with native ports.

This change allows surrogate code units in messages to/from native
ports and supports them in the UTF-8 encoding used on the Dart_CObject
structure string representation.

asiva@google.com b7673910ab Fix for issue 6359 - Make snapshots platform independent. 
The issue previously was that an instance size was stored a
size in bytes, similarly field offsets were stored as an offset
in bytes. This caused issues when generating the snapshot on
one platform and reading it on another platform.
The VM has been changed to store the instance size as a size in
words and the field offset as an offset in words.

srdjan@google.com 7375693321 In optimized code use IC calls for instance calls that have no IC data instead of deoptimizing. The optimized IC call increments usage counter and reoptimizes optimized function if the threshold is met. 
Recognize closure calls and mark them in ICData. Closure calls do not populate ICData, i.e., number of checks is always 0 (unless mixed closure calls with regular instance calls). Therefore closure IC calls do not count for reoptimization.

ajohnsen@google.com 970cc5ba68 Move JSSyntaxRegExp to core as a private member. This removes the last refrences to dart:coreimpl. 
After this cleanup, RegExp no longer have a const constructor. Use 'new
RegExp(...)' from now on.
