That was the last IND node on the LHS of a struct assignment without structHandle/known size.
There are small regressions because we now create
NULLCHECKnodes where before we were keepingADDR(INDthat rationalizer was destroying.Edited: The diffs are small and they are minopts only (don't create INDEX_ADDR in other cases, thanks @erozenfeld). The issue is similar to #44087 but because it minopts we won't delete the extra node even when the issue is fixed.
