Optimize loads from variables that might be shadowed by variables
...
introduced by eval.
In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call. Instead, we verify that the
context extension objects have not been created and perform a direct
load.
Not implemented for ARM yet and the scope resolution code could use
some better abstractions. I'd like to do that in a separate
changelist.

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.

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.
