Note that until everything is OStream-based, there are a few places
where we have to do some impedance matching. A few accessors had to be
const-corrected on the way.

addd35df56 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.

we need to be able to use different stubs (with a different number of

3cf157b43b Inline zero argument array constructor. 
patch from issue 54583003 (dependent code).

Zero arguments - very easy

1 argument - three special cases:
  a) If length is a constant in valid array length range,
     no need to check it at runtime.
  b) respect DoNotInline feedback on the AllocationSite for
     cases that the argument is not a smi or is an integer
     with a length that should create a dictionary.
  c) if kind feedback is non-holey, and length is non-constant,
     we'd have to generate a lot of code to be correct.
     Don't inline this case.

N arguments - one special case:
  a) If a deopt ever occurs because an input argument isn't
     compatible with the elements kind, then set the
     DoNotInline flag.

9d6dddb9ae Simplify behavior of code stubs that accept a variable number of stack 
arguments in addition to their parameters. Before, we'd add a special
variable to the environment with the value of a register with the
number of arguments. Now, that register just appears as a parameter to
the code stub.

6f75e92902 Add initial hydrogenized NewStringAddStub. 
The new stub is enabled via the --new-string-add flag, which is
disabled by default. For now, it's only a stripped down version
of the native StringAddStub, it's still work-in-progress.
