  Log Message:
  -----------
  [RISCV][SelectionDAGBuilder] Fix crash when copying a v1f32 vector between basic blocks.

On a rv64 without f32 or vector support, this will be passed across
the basic block as an i64. We need use i32 as an intermediate type
with bitcast and anyext/trunc.

Fixes PR58025
