8ab6832203 Add "has fast elements" bit to maps and use it in inlined keyed loads. 
A potential issue with this change is creating lots of maps when
objects flip between fast/slow elements modes.  We could add special
transitions to avoid this.  Yet testing this on our benchmarks, gmail,
and wave seems to indicate that this is not a real problem.

927750571c Remove redundant checks in and around GenerateDictionaryLoad. 
Similar or duplicate checks are scattered around the code before doing the dictionary load. 
Also the entire branch in GenerateCallNormal that handles global/builtin receiver is 
guaranteed to bail out from GenerateDictionaryLoad, so there is no point in generating it at all.

The purpose of the patch is:
- making C++ code more compact and transparent,
- not generating dead code. 

There is a tiny performance gain. The patch is ia32 only for now.

Please tell me if I am missing anything.

3cafa65462 Track ascii-ness of data in externalized strings. 
If a two-byte string only contains ascii characters, then we can save
memory when flattening a cons string containing it. Similarly we can
use this in Array.prototype.join implementation. To track this a new
bit is added to instance type. This bit is used as a hint in generated
code and in runtime functions.

To enable testing a new V8 extension is added controlled by
--expose-externalize-string flag.

e045ca6898 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.

634fb9152c More precise break points and stepping when debugging 
Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required.

In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted.

Added break locations to the true and false part of a conditional expression.

Added stepping tests to cover more constructs.

These changes are only in the full compiler.

Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.
