This is a partial revert of #145939 (I've kept the BUILD_VECTOR(FREEZE(UNDEF), FREEZE(UNDEF), elt2, ...) canonicalization) as we're getting reports of infinite loops (#148084). The issue appears to be due to deep chains of nodes and how visitFREEZE replaces all instances of an operand with a common frozen version - other users of the original frozen node then get added back to the worklist but might no longer be able to confirm a node isn't poison due to recursion depth limits on isGuaranteedNotToBeUndefOrPoison. The issue still exists with the old implementation but by only allowing a single frozen operand it helps prevent cases of interdependent frozen nodes. I'm still working on supporting multiple operands as its critical for topological DAG handling but need to get a fix in for trunk and 21.x. Fixes #148084
