  Log Message:
  -----------
  [RISCV] Make PseudoReadVL have the vtypes of the corresponding VLEFF/VLSEGFF.

The patch make PseudoReadVL have the vtypes of the corresponding VLEFF/VLSEGFF.
It's useful to get the vtypes of locations of PseudoReadVL without finding the
corresponding VLEFF/VLSEGFF.
It could simplify optimizations in RISCVInsertVSETVLI like D123581.
