The Itanium ABI effectively specifies how to lower the C++ ABI to an assumed C ABI, and the C ABI is given by what is known as the "psABI" (processor-specific ABI).
The (not-most-recent) x86-64 ABI is here: https://raw.githubusercontent.com/wiki/hjl-tools/x86-psABI/x86-64-psABI-1.0.pdf https://raw.githubusercontent.com/wiki/hjl-tools/x86-psABI/x..., and it does actually explain how to pass __int128.
