This reverts the change of array.js in r20839 and recovers 38%
performance regression of DOM-Search case in Browsermark2.0. There is
no performance impact on JavaScript benchmarks (Octane, Kraken and
SunSpider).

port r22011

original commit message:
  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
