changes how non-equality is evaluated
absl::c_mismatch is based on std::mismatch, which requires that its
iterators' reference types meet the requirements of
Cpp17EqualityComparable[1]. The previous CL mistakenly wrote
absl::c_mismatch using `*first1 != *first2` which assumes that the
reference types model std::equality_comparable[2] (which was only added
in C++20).
This CL reverts that behaviour.
