  Log Message:
  -----------
  [ValueTracking] Update `Ordered` when both operands are non-NaN. (#143349)

When the original predicate is ordered and both operands are non-NaN,
`Ordered` should be set to true. This variable still matters even if
both operands are non-NaN because FMF only applies to select, not fcmp.

Closes https://github.com/llvm/llvm-project/issues/143123.
