and only moved to destination on non-overflow in order to preserve source

This also fixes a bug in GetOwnProperty in runtime.cc discovered by
the new test cases. That part of the code was not testable before
since we had no way of correctly defining properties on elements.

Generating code for function return on ARM is now aligned with the other platforms. The first non-shadowed return statement encountered will emit code for function return and all other returns including the fall through at the bottom of a function will jump to that.

Naive algorithm for to update RSets for a span is rather inefficient
as it performs many unnecessary operations (retrieving a mask, updating
it with the same bit as many pointers go into a single region).

from pushing to chromium, a new flag for enabling code flushing,
--flush_code, is introduced with this change (defaulting to false).

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.
