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. Second try after #133130 was reverted by #133331 due to it affecting reverted test files
