[CodeGen] Compute DT/LI lazily in SafeStackLegacyPass. NFC. We currently require SCEV, which requires DT/LI. Those are expensive to compute, but the pass only runs for functions that have the safestack attribute. Compute DT/LI to build SCEV lazily, only when the pass is actually going to transform the function.
