Support object literal map caching for literals with keys that are array indices.
...
The caching code used to require that all keys in the literal were symbol strings
in order to be able to cache object literal maps.
Relaxed this requirement to allow array indices as well (as in { "1": "one", two: "two" }).
Changed the way 'number_of_properties' is calculated so that redundant property slots are not
allocated for array indices.

Better handling of stepping out of a function
...
With the change in r4820 all return statements are now breakable like any statement, so stepping will stop before the return statement actually returning from a function. With this change the position when breaking in the function return (after executing the return statement) will be the actual end of the function. At this point the return value is available as it saved to the stack by the debug break at return handling. Added information on the actual value returned from the function to the debugger.
