  Log Message:
  -----------
  [LegalizeTypes][RISCV] Support scalable vectors in SplitVecRes_BITCAST/SplitVecOp_BITCAST. (#88590)

Instead of bitcasting to a scalar integer, try to split the other vector
type that is legal. We already handle the case where both types need to
be split.

Fixes #88576
