I don't know, maybe we can try to ask rvv-intrinsic-doc define so many tuple types and try to
make them reduce the api && tuple types?
I am going to remove all FP16 vector to see whether we can reduce machine modes <= 256.
I think it may be probably helping to fix that.

To put it another way. Why does RISC-V have so many more modes than
AArch64.
