The IC exposes a register definition.
...
Centralize a register definition in an IC that provides:
1) symbolic names for the register (like, edx == receiver)
2) defines ordering when passed on the stack
Code that implements or uses the IC should use this definition instead of "knowing" what the registers are. Or at least have the definition to validate it's assumptions.
As a side effect of avoiding runtime static initializers (enforced by tools/check-static-initializers.sh, neat), I gave ownership of the registers array to CodeStubInterfaceDescriptor. This prompted a cleanup of that struct.

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.

CodeStubs contain their corresponding Isolate* now. (part 2)
...
This CL mechanically removes all useless Isolate* parameters from code
stub functions, making things quite a bit simpler.

FastNewClosureStub failed to load the cached literals array.
...
Also, less efficient code was generated because of negative keyed load
offsets. I changed this to benefit from HLoadKeyed dehoisting.
