Yingwei Zheng b1b065f2bf [ValueTracking] Refactor isKnownNonEqualFromContext (#127388) ...

This patch avoids adding RHS for comparisons with two variable operands
(https://github.com/llvm/llvm-project/pull/118493#discussion_r1949397482).
Instead, we iterate over related dominating conditions of both V1 and V2
in `isKnownNonEqualFromContext`, as suggested by goldsteinn
(https://github.com/llvm/llvm-project/pull/117442#discussion_r1944058002).

Compile-time improvement:
