[Clang][RISCV] Simplify RVV intrinsic policy suffix

Authored by eopXD on Jan 18 2023, 6:51 AM.



This patch works towards the simplification proposal [0] of Nick
Knight. After this patch, we have reduced the hierarchy of intrinsics
from two sets (non-policy and policy) into a single set, with a general
assumption that policy behavior is agnostic unless specified.


Pull Request: riscv-non-isa/rvv-intrinsic-doc#186.

Depends on D141796.

@kito-cheng I think the removal of HasTailPolicy and HasMaskPolicy here and under SemaRISCVVectorLookup.cpp, RISCVVEmitter.cpp should resolve your concern on these two attributes blending into the Policy object.
