  canonicalize maps for object literals. JSON objects
  with the same set of properties names will then
  share the same map.
  This reduces the amount of generated code associated 
  with object literals.
- Added a flag canonicalize_object_literal_maps.
  (default true)
- Changed the format of a function's literal array.
  Only the global context is now stored in the literal prefix.

Also, make sure to set the name of the function to anonymous after the
fact so that recursion through the name anonymous is not allowed and
so that global variables called anonymous are not shadowed.

Avoid the KMP overhead for simple indexOf() operations.  Will look into evaluating the best cutoff between a simple search and KMP in the future.  This improves some simple operations ~1.5x.

Don't try an indexOf() when the search string is bigger than the string.  The current code will spend a bunch of time trying to match, even though we should know a match is impossible.

TryFlatten is inlined, while Flatten is not.  Make an optimization to avoid the call to Flatten when we're already flat.  This gives me 5% on some simple indexOf experiments.

Do not clear the code cache for the builtins object.  If there was a

until a possible debug break location is reached. Currently this is call sites
with calls to code objects and JS return. Source position information in the
code therefore no longer refers to the "first" instruction generated for a
given source position (which was not the case defered code anyway) but to the
first break location after that source position was passed (again defered code
always start with source position information). This doesn't make a difference
for the debugger as it will always be stopped only at debug break locations.
However, this makes the life of the peep-hole optimizer much easier as many
oportunities for posh/pop eliminations where previosly blocked by relocation
information already written to the code object.

Two types of source positions are still collected. Statement positions indicate
the position of the start of the statement leading to this code and (plain)
positions indicate other places typically call sites to help indicate current
position in backtraces. The two different types of positions are also used to
distinguish between step next and step in.

Runs all the tests (including debugger tests) as before.

Moved the checking for the FLAG_debug_info to one place.

I will do the same changes to the ARM codegenerator in a seperate changelist.

occured.  After a monomorphic prototype failure has been detected,
other monomorphic inline caches for the same type will have a code
object in the map's code cache which is not the current target.  We
recognize this case and use the code object that is in the cache
