Log: 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.
