This change does two things.

First, it moves the utilities for the RISCVMaskedPseudoInfo table to RISCVInstrInfo.h/cpp (from SDAG ISEL).  This is partly because I have another change which might use it, but mostly because I wanted it close to the comment describing its purpose.

Second, I tried to give a rough overview of our current pseudo structure.  I'm mostly focused on the policy handling bits - since that's what I'm in the process of changing - but touched on the other dimensions in the process of framing it.
