X87: Added vector-based loadic hydrogen stubs. Not yet callable.

port r23405.

original commit message:
  Added vector-based loadic hydrogen stubs. Not yet callable.
  The next step is to integrate the use of vector[slot] into the IC
  infrastructure so it can do the right thing for a vector-based ic.
   Then these stubs can be installed. For now, they immediately bail
   out to the miss handler.
