  Log Message:
  -----------
  [RISCV] Add lowering for scalable @llvm.riscv.masked.strided.load/store

The code previously assumed fixed length vectors; make the relevant code conditional.

Having the lowering in place is neccessary for an upcoming change to generalize scatter/gather matching to scalable vectors.

  Log Message:
  -----------
  [RISCV] Pattern match scalable strided load/store

Very straight forward extension of the existing pattern matching pass to handle scalable types as well as fixed length types. The only extra bit beyond removing a bailout is recognizing stepvector.
