Refactor BinaryOpIC to be able to use different stubs.
...
Previously BinaryOpIC and BinaryOpStub were pretty much interdependent.
However, in order to use allocation sites for string adds on-demand,
we need to be able to use different stubs (with a different number of
register parameters, via trampolines) depending on the BinaryOpIC state.

Move responsibility for definition of ExtraICState bits into the ICs.
...
Currently it's in the Code object for some ICs and in ICs for other ICs.
This should make it easier to alter bits as needed.
2) Recover an extra bit in the code object to give us 6 bits for the extra ic state. We'll need it soon to store contextual state.
3) Cleanup code that treated StrictMode enum and ExtraICState enum as interchangeble.

Revert "Convert UnaryOpStub to a HydrogenCodeStub"
...
The problem is the HCallConstantFunction which is not context sensitive, so we leak the builtin. We first need a Hydrogen version of __ IvokeBuiltin.

Generate StoreGlobal stubs with Hydrogen

- Constants globals are inlined into Hydrogen code using code dependencies that invalidate the Crankshafted code when global PropertyCells or the global object change.
- The more general case generates code that is just as good as the hand-written assembly stubs on all platforms.
