Adjust hydrogen handling of function.prototype to be based on map feedback. Handle non-instance prototype loading using an IC rather than in the hydrogen instruction. In the future, remove the special instruction and replace by multiple hydrogen instructions.

66f0df5a18 Added an Isolate* field to NoTrackDoubleFieldsForSerializerScope, PlatformFeatureScope and BinaryOpIC::State. 
The serializer state and even the CPU features will be per-Isolate
later. Currently we get away with global state, because mksnapshot
runs single-threaded and has only 1 Isolate, but this will change.
Furthermore, these changes are yet another prerequisite for removing a
catch-22 at initialization time when we try to enable serialization.

This CL is similar in spirit to r20919, BTW.

dd30db9021 CodeStubs contain their corresponding Isolate* now. (part 1) 
This is a purely mechanical change, adding an Isolate* to the CodeStub
constructor and a corresponding field plus a getter. A few methods in
CodeStub and its subclasses can be simplified now, but this is done in
a separate CL.

The underlying reason apart from simplicity is that deep down in the
call chain we need to detect if the serializer is active or not. This
information will be part of the Isolate, not a global variable with
funky synchronization primitives around it (which is fundamentally
wrong and the underlying cause for race conditions and a catch-22
during initialization).

535f3427ca Pretenure call new support. 
When FLAG_pretenure_call_new is on, we emit mementos on new object creation
in full code, and consume the feedback in crankshaft. A key difference in the
generated code for stubs is the allocation of an additional type vector slot for the
CallNew AST node, which simplifies the CallConstructStub and CallFunctionStub
considerably.

Some performance tuning still needs to be addressed, therefore the flag is off at
this moment, though fully functional. The goal is to remove the flag as soon as
possible, which allows much code deletion (yay).

dd28969c1c Continued fix for 351257. Reusing the feedback vector is too complex. 
Attempting to re-use the type feedback vector stored in the
SharedFunctionInfo turns out to be difficult among the various cases.
It will be much easier to do this when deferred type feedback processing
is removed, as is in the works.

Created bug v8:3212 to track re-introducing the optimization of reusing
the type vector on recompile before optimization.

The CL also brings back the type vector on the SharedFunctionInfo.
