Nikita Popov ebc3162468 [ValueTracking] Handle more non-trivial conditions in isKnownNonZero()
In 35676a4f9a536a2aab768af63ddbb15bc722d7f9 I've added handling for
non-trivial dominating conditions that imply non-zero on the true
branch. This adds the same support for the false branch.

The changes in pr45360.ll change block ordering and naming, but
don't change the control flow. The urem is still guaraded by a
non-zero check correctly.
