[RISCV] Sink splatted fpext operands (#125800)
We sink splatted operands in codegenprepare to help match .vx/.vf
patterns. This extends it to also splat any fpext so that we can match
widening vfwadd.vf/vfwadd.wf patterns too.
Some instructions don't have .wf forms so there's no benefit to sinking
the fpext. For simplicity this sinks them anyway and lets
earlymachine-licm hoist them back out.
