46023fb742 Fix for off-by-one when initializing a constant or function

47d1298236 Change the handling of catch blocks to use context extension objects 
instead of normal JSObjects.

This ensures that __proto__ and accessors on the Object prototype do
not interfere with catch scopes.  Also, it fixes the bug that catch
variables were not DontDelete (issue 74).

Next step is to create special lookup routines for context extension
objects and remove the special handling of context extension objects
from the general javascript object lookup routines.

3f383346aa Inline array loads in loops directly in the code instead of always 
calling a stub.  The map to check against is unknown when generating
the code, so we patch the map check in the IC initialization code.

Loop nesting is currently not tracked on ARM.  I'll file feature
request bug reports for implementing this on ARM and add the number to
the TODOs before I commit.

b3dd6b686a 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.
