We should probably improve tcg_gen_not_vec to try NOR. This would support loongarch64,

Hmm, no. The tcg optimizer does better when NOT is supported directly.
There is a whole series of fold_*_to_not patterns.
It's what I get for looking at this for a long time.
Anyway, it would be good for LSX to expand NOT(x) via NOR(x,x).
