Could you please purpose this implement in rvv-intrinsc-doc first?
I think this feature need to have discussion because store to nullptr is UB but we are making it as defined behavior only for these intrinsics.
Personally I like they have consistent behavior and in document side we just make a note for users that vl should not be a null pointer.
