8ff53a8d62 X87: The IC exposes a register definition. 
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

8313c523b3 Optimize Map/Set.prototype.forEach 
Instead of using an iterator result object and an entries array
(for Map) we introduce a new runtime function that uses an array
as an out param.

On the Map ForEach perf test this leads to a 2.5x performance
improvement. On the overall Map and Set tests this leads to a 18%
and 13% improvement respectively.
