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

Port r23405 (12573f34)

Original commit message:
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.
