[SelectionDAG][RISCV] Move VP_REDUCE* legalization to LegalizeDAG.cpp. (#90522)
LegalizeVectorType is responsible for legalizing nodes that perform an
operation on each element may need to scalarize.
This is not true for nodes like VP_REDUCE.*, BUILD_VECTOR,
SHUFFLE_VECTOR, EXTRACT_SUBVECTOR, etc.
This patch drops any nodes with a scalar result from LegalizeVectorOps
and handles them in LegalizeDAG instead.
This required moving the reduction promotion to LegalizeDAG. I have
removed the support integer promotion as it was incorrect for integer
min/max reductions. Since it was untested, it was best to assert on it
until it was really needed.
There are a couple regressions that can be fixed with a small DAG
combine which I will do as a follow up.
