43d0ed048d Implements a new API to set a function entry hook for profiling. 
Exposes a new API; V8::SetFunctionEntryHook.
If a non-NULL function entry hook is set, the code generator(s) will invoke on the entry hook at the very start of each generated function.

d8c7a03a3a Grouping all map creation code. 
- Now tunnel all descriptor changes through methods on the map
- Renamed CopyDropTransitions to regular Copy since we always "drop transitions" on copy anyway.
- Merged and moved elements transition map creation.

3b5a6ef2e7 Removing LookupTransition from LookupRealNamedProperty and related utility functions. 
Callsites now have to manually lookup transitions if required. This
avoids unnecessary overhead of looking up transitions when we don't need
them. This also allows us to use IsFound() in many places where
IsProperty() was required previously.

11e5c9e281 Removed transitions from the accessor pair descriptors. 
AccessorPair related transitions are now also stored as single map links, simplifying the code that handles transitions. AccessorPairs can now be shared between descriptor arrays, since they can only be mutated after another transition anyway; during which the pair is copied before writing.

65e7a14973 Handle setters on the prototype chain efficiently by default. 
Note that changes on the prototype chain should already be handled by
StubCompiler::CheckPrototypes, if not, it is a bug there and not in
LookupForWrite. Furthermore, neither test262 nor WebKit layout tests hint at a
compability issue, so it should be safe to remove a redundant check.

The good point about this CL: It improves Box2D's performance by 22%.

d51b6826dc MIPS: Ensure that all descriptors have a valid enumeration index, and replace NextEnumIndex with LastAdded. 
Port r12042 (ce65764e)

Original commit message:
The LastAdded points to the descriptor that was last added to the array. From the descriptor we can deduce the NextEnumerationIndex. This allows us to quickly find the property that we are transitioning to, which is necessary for transition-intensive code, eg JSON parsing.

b8a7abd1fc Perform HasFastProperties check on prototypes when computing call targets in Crankshaft, part 2. 
The previous fix was for "real" calls, this one is for getters. It is a bit
unfortunate that this has to be fixed twice: We should really break up
Call::ComputeTarget into a predicate and 1 or 2 getters, so code can be reused.

The regression test has been modified a bit to make things more uniform.

e26128ac63 Fix bug in CompilationHandlescope constructor. 
This will never be triggered in the state v8 is currently in, but will crash v8 when multiple DeferredHandles are queued up during parallel compilation.
