1ce28eda0b - Expose CanvasPixelArray functionality directly in JavaScript 
indexed property accesses.

  at least we do not have to leave the VM to access bytes.

2183309385 Introduce a external allocation limit. 
If V8 is holding on to a lot of external memory, we attempt to clean
it up even if we do not get an allocation failure.  Since tiny V8
objects can hold on to a lot of external memory, we might run out of
external memory while waiting for a normal allocation failure.

d52990b2e2 Add a trace_gc_verbose flag. 
The flag is only turned on when --trace_gc is one. It prints out used and available bytes in each space. To enable it, ENABLE_LOGGING_AND_PROFILING must be defined.

This is a mini version of --heap_stats, but don't need DEBUG macro to be turned on.

d0c35af612 Create a new paged heap space for global property cells. The new 
space is similar to map space in that it has fixed-size objects.  A
common superclass for a space with fixed size objects is used for the
map space and cell space.

Allocate all cells in cell space.  Handle it during all GCs.  Modify
the free-list node representation (so that the size is not at a fixed
offset in all cells) to allow two-pointer free-list nodes.  Clean up
some stuff in the MC collector.

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.

8dffcb9efa Flush ICs when adding setters to an object or setting a __proto__ to 
an object that holds a setter.  If there are no store ics then no
flushing is done.  The implementation has been tweaked so that no ICs
are cleared during normal context creation.
This may cost us some performance but I'm submitting it as it is and
if there are problems we can either decide to be smarter about when,
what and/or how we clear, or back this change out altogether.

Moved the registrered debug event listener from the context to a global handle in the Debugger class. Storing it in the context did not make much sense.
