Ensure that all objects that had the same map before attaching an external array have the same map once the external array is attached.

e21d76a0e3 1. Added support for object printing for release mode using the
objectprint=on (defaults to off) option (which defines OBJECT_PRINT).
2. Added the ability to print objects to a specified file instead of
   just stdout.
3. Added a use_verbose_printer flag (true by default) to allow some
   object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
   empty char vector.

Patch by Mark Lam from Hewlett-Packard Development Company, LP

421db370d9 Preserve constant function transition when adding the same function.
This should help in cases like:
function Constructor() {
  this.foo = constFunction;
  this.bar = "baz";
}

for (...) {
  o = new Constructor();
  // Constant call IC will work.
  o.foo();
  // Inlined property load will see the same map.
  use(o.bar);
}

This change also fixes a latent bug in custom call IC-s for strings
exposed by string-charcodeat.js.

806c15e4b5 Remove the LookupResult IsValid method because it is confusing.
Replaced IsValid by IsPropertyOrTransition and used IsProperty in most
of the places where IsValid was used before.  Most of the time when
inspecting a lookup result we really want to know if there is a real
property present.  Only for stores are we interested in transitions.

00cdc3f1a3 Remove the descriptor stream abstractions.
The abstractions have led to bugs because it looks like descriptor
streams are GC safe but they are not.

I have moved the descriptor stream helper functions to descriptor
arrays and I find most of the code just as readable now as it was
before.

a54a4ada5c Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

6941a4f389 Collects unused maps that are only kept alive by map transitions.
If a map has descendents in the map transition tree that are alive,
it is kept.  Only maps such that they and all their descendants
have no live objects are collected.  This happens in mark-sweep and
mark-compact garbage collections.

  the script.
- Remove runtime calls to get number constants. Remove Heap roots for
  some special numbers.
- Fix typo in accessors.h.
- Changes CopyMap to not copy descriptors.  Adds
  CopyMapRemoveTransitions that copies non-transition descriptors.
  Changes interface of DescriptorArray::Copy operations to simplify
  them.

769cc962a0 Improved performance of unary addition by avoiding runtime calls.
Fixed the handling of '>' and '<=' to use right-to-left conversion and left-to-right evaluation as specified by ECMA-262.

Fixed a branch elimination bug on the ARM platform where incorrect code was generated because of overly aggressive branch elimination.

Improved performance of code that repeatedly assigns the same function to the same property of different objects with the same map.

Untangled DEBUG and ENABLE_DISASSEMBLER defines.  The disassembler no longer expects DEBUG to be defined.

Added platform-nullos.cc to serve as the basis for new platform implementations.
