Add empty scheduler info and `NoItinerary` to the`MipsAsmPseudoInst`. These pseudo-instructions are never used by codegen. `NoItinerary` and empty scheduler info allow to reduce number of "No schedule information for" and "lacks information for" errors in case of marking a scheduler model as complete.

This patch is one of a series of patches. The goal is to make P5600 <https://reviews.llvm.org/P5600> scheduler model complete and turn on the `CompleteModel` flag.
