We already infer this in IPSCCP (which runs very early, so cannot benefit from inlining and simplifications) and SCCP (which runs without PredicateInfo, so does not use assumes). Do it in CVP as well, so it can handle cases that IPSCCP/SCCP can't. Fixes https://github.com/llvm/llvm-project/issues/98946 (everything apart from f2, where the assume is dropped by the frontend).
