Use DART_CHECK_VALID has been incorrect since the introduction of Isolate.kill and Dart_Cleanup because it crashes when given an unwind error.
Remove long-broken FullSnapshot1 test.

- Change the stack overflow check in the prolog to load the stack limit
from the THR register, this removes the back to back dependent loads to
load the stack limit from the Isolate structure

Thread barrier with:
* fixed (at construction) number n of participating threads {T1,T2,T3,...,Tn}
* unknown number of rounds.
Requirements:
* there is some R such that each participating thread makes
R calls to Sync() followed by its one and only call to Exit().
Guarantees:
* for any two threads Ti and Tj and round number r <= R,
everything done by Ti before its r'th call to Sync() happens before
everything done by Tj after its r'th call to Sync().
Note:
* it's not required that the thread that constructs the barrier participates.

Remove potentially dangerous (but currently unused) Isolate::stack_limit() accessor.
Add method to test whether interrupts are scheduled, using relaxed memory ordering.
Document and test correct usage by adding a new unit test.
This will be used to periodically check for safepoints in C++ (which will then be equivalent to our generated code).

Cache a pointer to the isolate's Heap in the Thread object
and use it in generated code for allocation.
Change generated allocation code to load allocation-top and
end via THR (THR->heap.top). This is slightly slower than
embedding the address, but faster than loading it
via the Isolate (THR->isolate->heap.top)

compatible with webkit and will allow for easy externalization of
strings. One byte strings are retained for pure ASCII strings.
(The language specification was changed recently to reflect this as
follows "A string is a sequence of UTF-16 code units").
- Remove four byte string class and all references to it.
- Rename some of the string functions in Dart API to make them
consistent and better describe the underlying functionality

big global change, so let me explain in more detail. This refactoring CL does
the following:
- moves all the dart code for isolates in a common library (lib/isolate)
- changes frog to understand 'dart:isolate' imoprts by loading the code from the
location above.
- changes the vm to undernstand 'dart:isolate' imports by creating a separate
library that is part of the bootstrap. This follows the same code-structure
that Todd suggested in his CL introducing the mirror library
- changes dartc to use the shared isolate library as the source of truth for
type checking. I left around some of the internal js code in dartc so that the
backend continues to work for apps that don't use isolates.
- changes all tests that use isolates to import the library explicitly (this is a large bulk of the files in this CL)
- changes test status for tests we can't fix in this repo (e.g. co19)
- splits the isolate library code to make it possible to preserve some tests
without exposing internal types (e.g. tests about
serialization/deserialization)
- changes the create_sdk script to copy the isolate library to the sdk
- includes the isolate library in dartdoc
I'll wait for at least one lgtm from each area (dartc, vm, frog, sdk)
There is one important pending thing this CL doesn't do:
- update test_runner.dart: This should be updated next time we upload the new
binaries to tool/testing/bin
- dartium specific changes: Vijay, is there anything I need to do for dartium?

The purpose of this change is twofold:
1. Source in the bin directory can now use the same assertions as
source in the vm directory. The ASSERT macro used by the code
in runtime/bin was just defined to use assert from the standard
C library.
2. Moving other implementation parts from runtime/vm to
runtime/platform (e.g. classes Monitor and Mutex) for sharing
between runtime/bin and runtime/vm will be easier as these
implementations rely on these assertion macros.
Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.
All the code for asserts is still in the dart namespace.
Also re-arranged the order of includes to be alphabetically in
the files touched.

Terminology change: invalid handles are now called error handles.
Unhandled exceptions used to be a kind of valid handle. Now they are
a kind of error handle.
For the Dart_Invoke* functions, this means that the standard
error-checking blob drops from two tests to one test and is
harder to mess up.
Many other Dart api functions (Dart_ToString, for example) previously
dealt with unhandled exceptions by turning them into terse error
messages. Now these functions preserve information about the
exceptions and generate better error messages.
Changed Dart_HandleMessage to return success/failure. It seemed to fit.
--
Details:
Dart_IsValid becomes Dart_IsError (negated sense).
Dart_GetError now knows how to print a stack trace semi-nicely.
Dart_ExceptionOccurred -> Dart_IsUnhandledException.
Renamed ApiFailure class to ApiError to fit better.
ApiError now has a "data" pointer that points to either an error
message string or to an unhandled exception object.
Documentation changes aplenty.

- Dart_Result is gone. Dart_Handle mostly replaces it.
- Name/signature changes
- IsValidResult -> IsValid
- GetErrorCString -> GetError
- many more...
- Make details of persistent handle freelist private.
- Add persistent "True" handle to api state.
Things I am not doing in this changelist:
