  Changed paths:
    M llvm/lib/Target/RISCV/RISCVISelLowering.cpp
    M llvm/test/CodeGen/RISCV/rvv/named-vector-shuffle-reverse.ll

  Log Message:
  -----------
  [RISCV] Narrow indices to e16 for LMUL > 1 when lowering vector_reverse (#104427)

The vector_shuffle lowering already does this to reduce register
