RISC-V: Support vfwnmacc/vfwmsac/vfwnmsac combine lowering
Similar to vfwmacc. Add combine patterns as follows:
For vfwnmsac:
1. (set (reg) (fma (neg (float_extend (reg))) (float_extend (reg))) (reg) )))
2. (set (reg) (fma (neg (float_extend (reg))) (reg) (reg) )))
For vfwmsac:
1. (set (reg) (fma (float_extend (reg)) (float_extend (reg))) (neg (reg)) )))
2. (set (reg) (fma (float_extend (reg)) (reg) (neg (reg)) )))
For vfwnmacc:
1. (set (reg) (fma (neg (float_extend (reg))) (float_extend (reg))) (neg (reg)) )))
2. (set (reg) (fma (neg (float_extend (reg))) (reg) (neg (reg)) )))
