Yes, thanks for filing this bug separately. The patch doesn't disable all of
those optimizations, of course I paid special attention not mess up with them.
The difference here is that we valueize, add stateme

If we specify the vector length to RVV and SVE:
https://godbolt.org/z/njvsqYWhn
Both can vectorize.
ARM SVE: -msve-vector-bits=128

The issue is that we only support integral vector types in fold_vec_perm_cst,
but fail to check for the same before calling it from fold_vec_perm.
