Factored the generation of JSON serialization from beeing part of the mirror objects into a seperate class. The purpose of this is to make it easier to change the serialization to contain object identification and references.

Added a test case for the script mirror and modified a number of the other mirror tests.

  the alternatives in a choice node.  The quick checks
  are conservative in the sense that they only detect
  failure with certainty.  Checks can do 2 or 4 characters
  at a time.
* Inline the quick checks to allow the alternatives to
  be checked without branching in the common case where
  they fail.

  ContextSwitcher::PreemptionReceived.
- Removed a leak of the semaphore in the ContexSwitcher thread, by removing

Refactored the recording of source position in the generated code. The code generator now has two methods

  void CodeForStatement(Node* node)
  void CodeForSourcePosition(int pos)

The first is used to indicate that code is about to be generated for the given statement and the second is used to indicate that code is about to be generated for the given source position.

Added position information for some statements which was missing whem.

Updated the code generator for ARM to emit source position the same way as for IA-32.

Added an assert to ensure that deferred code stubs will always have a source source position as if it has not it will take whatever source position before which makes no sense.

The passing test on ARM has only been tested using the simulator.
