RISC-V: Fix incorrect VTYPE fusion for floating point scalar move insn[PR111037]

void foo(_Float16 y, int64_t *i64p)
{
  vint64m1_t vx =__riscv_vle64_v_i64m1 (i64p, 1);
  vx = __riscv_vadd_vv_i64m1 (vx, vx, 1);
  vfloat16m1_t vy =__riscv_vfmv_s_f_f16m1 (y, 1);
  asm volatile ("# use %0 %1" : : "vr"(vx), "vr" (vy));
}
