X87: [interpreter] Switch passing of new.target to register.

  port 3d004eeab23c8b47bd9bdd2cc66434dcc19a1b2f (r32264)

  original commit message:
  This passes the new.target value in a register instead of through a
  side-channel via the construct stub. The interpreter entry trampoline
  stores this value in a bytecode register so that it can be accessed
  directly by the interpreter. The size of the interpreter stack frame
  hence grows by one slot.
