d759938461 Changed optimization from /Ox to the (more) commonly used /O2 (which includes 
/GF) in both SCons and Visual Studio build. There is not mesurable difference
neither in speed nor in code size.

Added whole program optimization to the SCons release build. This clutters the
linking of the samples a little with the option /LTCG. This option is not
strictly needed for linking, but if it is not specified the linker complaints
as it can see object files compiled with /GL and then restarts itself with
/LTCG which dosen't look very pretty.

Changed 'undefined' in ArraySort to 'void 0'. Also added regression test to catch the error.

016fcd4aff Fix issue 86 by keeping track of the fact that finally blocks 
are evaluated with an extra element on the stack, which needs
to be taken into account when breaking and continuing. 

I'll clean up the code and add an abstraction for manipulating
the break stack height in a future CL -- I want to try to get
rid of the separate local variable we keep around for the "state"
when running in a finally block.

e05eba857e - Added a map cache for literal objects. This will 
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.

ff4e9ea134 Make sure that the body of the function created by calling Function is 
on a line of its own.  This allows the body to be terminated by a
single-line comment.

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.
