RISC-V: Add pattern for vector-scalar floating-point min

This pattern enables the combine pass (or late-combine, depending on the case)
to merge a vec_duplicate into an smin RTL instruction.

Before this patch, we have two instructions, e.g.:
  vfmv.v.f       v2,fa0
  vfmin.vv       v1,v1,v2

After, we get only one:
  vfmin.vf       v1,v1,fa0

gcc/ChangeLog:

	* config/riscv/autovec-opt.md (*vfmin_vf_<mode>): Add new pattern to
	combine vec_duplicate + vfmin.vv into vfmin.vf.
	* config/riscv/vector.md (@pred_<optab><mode>_scalar): Allow VLS modes.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/vls/floating-point-min-2.c: Adjust scan
	dump.
	* gcc.target/riscv/rvv/autovec/vls/floating-point-min-4.c: Likewise.
	* gcc.target/riscv/rvv/autovec/vx_vf/vf-1-f16.c: Add vfmin.
	* gcc.target/riscv/rvv/autovec/vx_vf/vf-1-f32.c: Likewise.
	* gcc.target/riscv/rvv/autovec/vx_vf/vf-1-f64.c: Likewise.
