Subject: [PATCH 2/3] [VP] Refactor VectorBuilder to avoid layering violation.
NFC (#99276)
This patch refactors the handling of reduction to eliminate layering
violations.
* Introduced `getReductionIntrinsicID` in LoopUtils.h for mapping
recurrence kinds to llvm.vector.reduce.* intrinsic IDs.
* Updated `VectorBuilder::createSimpleTargetReduction` to accept
llvm.vector.reduce.* intrinsic directly.
* New function `VPIntrinsic::getForIntrinsic` for mapping intrinsic ID
to the same functional VP intrinsic ID.
