Rename the function to reflect its correct behavior and to be consistent
with `Module::getOrInsertFunction`. This is also in preparation of
adding a new `Intrinsic::getDeclaration` that will have behavior similar
to `Module::getFunction` (i.e, just lookup, no creation).
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.
VectorBuilder wraps around an IRBuilder and
VectorBuilder::createVectorInstructions emits VP intrinsics as if they
were regular instructions.
