Yingwei Zheng f16bff1261 [GVN][NewGVN][Local] Handle attributes for function calls after CSE (#114011) ...

This patch intersects attributes of two calls to avoid introducing UB.
It also skips incompatible call pairs in GVN/NewGVN. However, I cannot
provide negative tests for these changes.

Fixes https://github.com/llvm/llvm-project/issues/113997.
