Update with solution for the last commit issues with that looks more appropriate to me with just avoiding any vectors like [ operand, operand, op, operand] or [load, load, op, load] in a scheduling bundle, with this solution I have not noticed any bitcode regressions(efficiency) with provided testcase pr34619.ll. I have checked all list of issues from the previous build with this change.
