This only wins us around 1% in performance, but it makes the code more
compact.  We don't currently have a way to represent in the virtual
frame that a slot contains a value from the root array.  Adding this
would probably make the code more compact.

Android system provides a unique feature that it sends a notification to the
browser in low memory condition, and the browser cleans up cache and frees
resources. Forcing a GC in low memory condition can free DOM objects and also
can shrink the old spaces.

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.

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.

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.

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.

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.
