  -----------
  [RISCV] Add casts to isel patterns that produce more than 1 instruction.

We need explicitly cast to XLenVT to avoid tablegen picking i32.

If the SelectionDAG scheduler is used it can't find a register
class for i32 if i32 isn't a legal type.

Fixes #81192, but I might have missed some patterns.
