d3e457303e Add API callback for tracking allocated memory 
Allows the host application to provide a mechanism for notification and custom logging through a callback (set through the API V8::AddMemoryAllocationCallback and removed through V8::RemoveMemoryAllocationCallback), when V8 allocates ro frees memory. 

This replaces the current histogram data "V8.ExecutableMemoryMax" by allowing usage data to be logged by the application as required rather than always through V8. 

BUG=http://crbug.com/54222
TEST=Set the callback function with the API and cause V8 to allocate memory.

Patch by Paul Mehta <pmehta@chromium.org>

a9641176fd Remove assertion that is no longer valid in InitializeStringSearch. 
This assertion is no longer valid because r5380 changes the assumption
about the pat parameter.

In addition, we embed the no allocation part of StringSplit in a block
to reenable allocation later in that method.

f19d6133f2 Fix mozilla and debug check failures. 
This removes the expected failure of a mozilla test that we now pass
(an empty array is returned if Array.splice is called with no
arguments) and fixes debug check failure by allocating a new empty
array using AllocateEmptyArray if splice is called with zero arguments
(makes sure we can always create a handle).

19dc35c13f Force relinking of paged space if first attempt to recommit from space fails. 
That could improve chances for commit success as currently,
if we moved free pages out of order, we cannot shrink spaces.
However, when we experience problems commiting from space back, we should
use most of resources at our disposal.

Also get rid of currently unused parameter to DeallocateFunction.

3fb62235e3 Add functionality for finding code objects from a pc that points into 
the code object's instructions.

This allows us to find a code object using just the pc. This approach
uses a cache (PcToCodeCache) to make sure we don't continuously have
to iterate heap pages.

This change eliminates the need for cooking and uncooking of stack frames.

be5763fc4d Cleanup the way the debugger stores live registers when entering at a break 
The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max).

This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it.

Fix a missing live register when breaking at ARM keyed load.

7672338bc9 Fixes bug in Object.freeze and Object.seal causing them to misbehave when Array.prototype has changed. 
Object.freeze and Object.seal uses GetOwnPropertyNames which
returns an array with local property names. This array will also have
the additional properties defined on Array.prototype or
Object.prototype.

Note that, the implementation of GetOwnPropertyNames (when used as
Object.getOwnPropertyNames) is correct, since the spec says to create
a new Array (which would also have these properties).

6bd9d953dd Reapplying r5147 (caching maps for slow case objects). 
r5147 wrongly assumed that a code cache for a slow case map is always empty.
This patch solves this: whenever we attempt to add a stub to a map's code cache 
we check that this map is cached. If it is we give the object its own copy
of the map and only then modify the map.
