[SDAG] Limit sincos/frexp stack slot folding to stores chained to entry (#115906)
When the chain is not the entry node there is a risk the stores are within a (CALLSEQ_START, CALLSEQ_END), which when the node is expanded will lead to nested call sequences. It should be possible to check for this and allow more cases, but for now, let's limit this to cases where it's definitely safe. Fixes #115323
