Not really. Calls to those functions are generated by the compiler implicitly when a divisor operand is used and therefore we cannot annotate those calls. We'd have to use special accessors everywhere to replace the standard division operand (like we do for 64 by 32 bit divisions) but I doubt that people would accept that. You cannot just scan the binary for the appropriate branch opcode either as you may turn up false positives in literal pools.
