d0e76971a6 Change the way we handle backward jumps in the code generator. Keep 
the frame states of all the forward-entering frames that had merge
code generated.  At a backward branch, check if there is no merge code
or if we can reuse an existing merge block.

79aae815dd During the refactoring in r1461 and adding of script ids in r1468 the propagation of a boolean flag was missing. This caused the line numbers retreived through ScriptMirror objects to ignore the resource line offset information in the script. 
Added an explicit false parameter where the parameter was previously left out.

Added a test case for this.

90093ea868 Fix exception propagation problem where undefined was returned instead 
of an empty handle in case of an exception.  This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.

The issue is that exceptions are not rescheduled if they are
externally caught.  Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.

9d17b0d4c8 Whenever a script object is created it is assigned a unique id. Currently this id is assigned from an 32 bit integer counter. 
Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account.

This has the side effect that function break points are not converted into script break points for named scripts.

Show the script id in the D8 shell debugger when listing all scripts using the 'scripts' command.

ece2c03160 Fix issue 263: 
http://code.google.com/p/v8/issues/detail?id=263

Sharing the code to unlink the exception handler for a try/finally
causes us to try to merge virtual frames with different heights (due
to statements that keep state on the stack) at the entry to the unlink
code.

Avoid this by unlinking the handler separately for each exit from the
try block.

747e20c449 Mark the empty script object, the script for the empty function and the D8 utility script as native scripts. 
This is mainly to avoid these scripts showing up in the debugger when showing normal scripts.

Removed the check for the empty script in the debugger function returning loaded scripts as this check only filtered out the empty script from the debugger context and not empty scripts in all other contexts. Also this filter did not take the script for the empty function into account.

Due to constant folding of loop conditions, it is possible to have a
try/finally with no exits from the try block (eg, an infinite loop in
the try block).  In that case the code to unlink the try handler is
dead and should not be emitted.

e9e8628380 Revert revisions 1383, 1384, 1391, 1398, 1401, 1402, 
1418, and 1419 from bleeding_edge until we have a fix
for the crashers we see on the distributed test infra-
structure.

We know that revision 1383 is causing issues, but I 
had to revert some of the other recent RegExp changes
in order to get this part out.
