[PATCH] Fix fp16 checking in vector fp widen/narrow instructions

[Max Chou]

When SEW is 16, we need to check whether the Zvfhmin is enabled for the
single width operator for vector floating point widen/narrow
instructions. 

The commits in this patchset fix the single width operator checking and
remove the redudant SEW checking for vector floating point widen/narrow
instructions.

Max Chou (4):
  target/riscv: rvv: Fix Zvfhmin checking for vfwcvt.f.f.v and
    vfncvt.f.f.w instructions
  target/riscv: rvv: Check single width operator for vector fp widen
    instructions
  target/riscv: rvv: Check single width operator for vfncvt.rod.f.f.w
  target/riscv: rvv: Remove redudant SEW checking for vector fp
    narrow/widen instructions
