[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:
