Florian Hahn 950576bdf8 [GVN,NewGVN] Keep nonnull if K does not move. ... In combineMetadata, we should be able to preserve K's nonnull metadata, if K does not move. This condition should hold for all replacements by NewGVN/GVN, but I added a bunch of assertions to verify that. Fixes PR35038. There probably are additional kinds of metadata that could be preserved using similar reasoning. This is follow-up work.
