For Octane, the number of calls go down from 7341629 to 1947880, i.e. they are
reduced by more than 73%. TLS access is not especially cheap, so this exercise
seems worthwhile.

In more detail:
- Set observation bit for observed objects (and make NormalizedMapCache respect it).
- Mutation of observed objects is always delegated from ICs to runtime.
- Introduce JS runtime function for notifying generated changes.
- Invoke this function in the appropriate places (including some local refactoring).
- Inclusion of oldValue field is not yet implemented, nor element properties.

Also, shortened flag to --harmony-observation.

This fixes the positive lookup performed by these LoadICs, to use the
holder instead of the receiver to perfrom the lookup on. It also extends
this improvement to KeyedLoadICs. And it fixes a bug introduced for the
JavaScript getter case of a LoadIC.

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.

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%.

b008d99b11 Ensure that all descriptors have a valid enumeration index, and replace NextEnumIndex with LastAdded. 
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.

d7a5b7d5e2 Separating transitions from descriptors. 
In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array.

The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly.

Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.

Instead of overwriting non-live transitions with NULL_DESCRIPTORs, we remove them from the array by compacting the array (shifting live values to the left) and in-place trimming the array.

The descriptor array itself will be collected in the next GC.

c810016e77 Implement clearing of CompareICs. 
This allows CompareICs to be cleared during garbage collection to avoid
cross-context garbage retention through maps stored in CompareIC stubs
for the KNOWN_OBJECTS state.

71702e1da3 Improve performance of keyed loads/stores which have a HeapNumber index. 
Some GWT compiled code results in array access that has a heap number (e.g. -0)
as an index. Until now this would result in a generic IC.

For example:

a[-0] === a[0] or

a[0.25 * 4] === a[1]

This change detects heap numbers that are representable as a smi
and converts them. As a result we can still use the fast keyed monomorphic
ICs. Optimized code already handles keyed access with a double-key efficiently.

As a result the frame rate on the reported benchmark improves by roughly 2x.

4389c29cce Fix store IC writability check in strict mode. 
The store ICs should only check writability attributes for actual
properties and not for map transitions.

254d810a32 When transitioning LoadIC to megamorphic case place monomorphic stubs into stub cache. 
Otherwise if function is optimized immediately after transition type oracle will be unable to gather enough maps from stub cache and graph builder will emit HLoadNamedGeneric instead of HLoadNamedPolymorphic.
