c7b09aac31 Remove the dependency of Zone on Isolate 
Along the way:
- Thread isolate parameter explicitly through code that used to
  rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
  affected code
- Change Hydrogen New<> instruction templates to automatically
  pass isolate

0e16150d33 Better typing and type verification 
- Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
  (subsumes typing of constant cache, removing its typing
  side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
  with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.

To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.

4ec63ff97e Reland 
- "Switch inlining to use simplified instead of machine loads."
- "Add copy support in inliner."

Reland fixes:
 - size_t conversion for 64bit arches
 - Don't call front() on empty vector
   (triggers assertion on windows)
 - turbo_inlining now implies turbo_types, as
   it requires simplified lowering.

9803a72417 Unify MachineType and RepType. 
MachineType now tracks both the representation and the value type of machine quantities and is used uniformly throughout TurboFan.

These types can now express uint8, int8, uint16, and int16, i.e. signed and unsigned smallish integers. Note that currently only uint8 and uint16 are implemented in the TF backends.

670df5063b Implement representation selection as part of SimplifiedLowering. Representation selection also 
requires inserting explicit representation change nodes to be inserted in the graph. Such nodes
are pure, but also need to be lowered to machine operators. They need to be scheduled first, to
determine the control input for any branches inside.

This CL requires extensive testing. More tests to follow.
