[SelectionDAG] Handle more opcodes in isGuaranteedNotToBeUndefOrPoison (#147019)
Add special handling of EXTRACT_SUBVECTOR, INSERT_SUBVECTOR,
EXTRACT_VECTOR_ELT, INSERT_VECTOR_ELT and SCALAR_TO_VECTOR in
isGuaranteedNotToBeUndefOrPoison. Make use of DemandedElts to improve
the analysis and only check relevant elements for each operand.
Also start using DemandedElts in the recursive calls that check
isGuaranteedNotToBeUndefOrPoison for all operands for operations that do
not create undef/poison. We can do that for a number of elementwise
operations for which the DemandedElts can be applied to every operand
(e.g. ADD, OR, BITREVERSE, TRUNCATE).
