The memory leaks are all from the tests, not actually in V8.

Use virtually dispatched specialized scavengers instead of single generic ScavengeObjectSlow implementation.

Rollback of r5041 with assertion checking callback alignment removed. Map space is iterated in a special fashion during scavenges so special callback alignment is not required.

The main fix is for current_state() and external_callback() accessors.
I also applied memory access ordering on current_state_ modification,
mainly to reflect the fact that it is being shared among VM and profiler
sampler threads.

A few hot Date.prototype functions used to be implemented as
DateGetFoo calling GetFooFrom(this), and other callers of GetFooFrom
did repeated date value extraction.  In this change GetFooFrom
functions were inlined into the functions on the prototype and the
other callers switched to using date values directly.

to the runtime will both patch in the more specialized binary op
stub and calculate the answer.  This eliminates the need to call
both the rest of the binary op and the patching runtime call.  The
runtime routines are altered to be more agressive in returning
Smis so we don't get spurious heap numbers as inputs to binary ops
while we are patching the binary op ICs.
