intel/compiler: Use named NIR intrinsic const index accessors

Browse Source 
In the early days of NIR, you had to prod at inst->const_index[]
directly, but a long while back, we added handy accessor functions
that let you use the actual name of the thing you want instead of
memorizing the exact order of parameters.

Also rewrite a comment I had a hard time parsing.
