[DAG] visitEXTRACT_SUBVECTOR - accumulate SimplifyDemandedVectorElts demanded elts across all EXTRACT_SUBVECTOR uses (#133130)
Similar to what is done for visitEXTRACT_VECTOR_ELT - if all uses of a vector are EXTRACT_SUBVECTOR, then determine the accumulated demanded elts across all users and call SimplifyDemandedVectorElts in "AssumeSingleUse" use.
