198c4769f2 Unify and simplify the FastCloneShallowArrayStub 
- Don't bake in length/capacity into full codegen calls of stubs,
  allowing boilerplates to increase their capacity without regenerating
  code.
- Unify all variants of the clone stub into a single,
  length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
  therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

This CL mechanically removes all useless Isolate* parameters from code

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).

6b4d4b7287 Reland "Track field types.". 
This is an initial step towards tracking the exact types instead of just
the representations of fields. It adds support to track up to one map of
heap object field values, eliminating various map checks on values
loaded from such fields, at the cost of making stores to such fields
slightly more expensive.

Issues with transitioning stores and fast object literals in Crankshaft
fixed.

f66af4feb4 Refactor optimized in hydrogen only runtime functions. 
This splits all runtime function into 3 categories:
1) RUNTIME: implemented in runtime and called from both full and optimized code.
2) RUNTIME_HIDDEN: implemented in runtime, never called directly from JS builtins.
3) INLINE: inlined in both full and optimized code
4) INLINE_OPTIMIZED: inlined in optimized code, implemented in runtime for full code.
