After https://github.com/llvm/llvm-project/commit/97d4e96cc5ed614ae0412ef676462cd68859e048, optimizeMaskToEVL can only transform recipes that satisfy the following conditions:
1. The mask is header_mask.
2. The mask is header_mask && conditional_mask.
However, joining points can produce complex masks with or operations, not just logical_and. This prevents some recipes from being transformed into EVL load/store.
