I want to fork the GNU g++ compiler and add a new integer type, __int256_t.

Could someone please point me to the relevant files where __int128_t
is implemented? I've been searching the repository on Github but can't
find it.

You should clone the repo and use git grep, not github's search. That
will find it instantly. For github you need to search for the string
"__int128_t" (with quotes).

But __int128_t is just an implicitly-defined typedef, you probably
want to add the actual types __int128 and unsigned  __int128 instead.

You want to search for INT_N and __intN to see how non-standard
integer types are defined.
