* Modify intrin_rvv: Disable some existing types.

* Modify intrin_rvv: Reinterpret instead of load&cast.

* Modify intrin_rvv: Update load&store without cast.

* Modify intrin_rvv: Rename vfredsum to fredosum.

* Modify intrin_rvv: Rewrite Check all/any by using vpopc.

* Modify intrin_rvv: Use reinterpret instead of c-style casting.

* Remove all macros which is not used in v_reinterpret

* Rename vpopc to vcpop according to spec.
