The meta data update code looks fine to me.
================
Comment at: lib/Transforms/InstCombine/InstCombineSelect.cpp:1825
+ // MIN(~a, C) -> ~MAX(a, ~C)
+ auto moveNotAfterMinMax = [&](Value *X, Value *Y) -> Instruction * {
+ Value *A;
----------------
Can the operands_swapped passed as an argument?
