X87: [Interpreter] Add ForInPrepare runtime function which returns a ObjectTriple.

  port 84f8a506e204b1e70df5b9a8036cc97170e661fd (r33334)

  original commit message:
  Adds a ForInPrepare Runtime function which returns a triple of
  cache_type, cache_array and cache_length.

  This requires adding support to CEntryStub to call runtime functions
  which return a ObjectTriple - a struct containing three Object*
  pointers. Also did some cleanup of the x64 CEntryStub to avoid
  replicated code.

  Replaces the interpreter's use of the ad-hock InterpreterForInPrepare
  Runtime function with ForInPrepare in preparation for fixing deopt in
  BytecodeGraphBuilder for ForIn (which will be done in a followup CL).
