Pointers to these functions are used in comparisons.
Currently the compiler has to presume the worst for these,
namely that the functions are from another DSO and therefore
loads their addresses from the GOT (which also entails a
relocation entry that is processed at runtime, regardless
of whether the code using them is run or not). This changes
if these functions are declared as hidden.
