LOG: [CodeGen] Use std::tie to implement a comparison functor (NFC) (#140088)

std::tie simplifies the lexicographical comparison while making the
code a little more consistent within MIRPrinter.cpp as we have a very
similar comparison functor in MIRPrinter::convertCalledGlobals, about
30 lines below the code this patch touches.
