+/// \brief Match an 'unordered' floating point minimum function.
+/// Floating point has one special value 'NaN'. Therefore, there is no total
+/// order. However, if we can ignore the 'NaN' value (for example, because of a
+/// 'no-nans-float-math' flag) a combination of a fcmp and select has 'minimum'
+/// semantics. In the presence of 'NaN' we have to preserve the original
+/// select(fcmp(ult/le, L, R), L, R) semantics matched by this predicate.
+///
+/// max(L, R) iff L and R are not NaN
+/// m_UnordFMin(L, R) = L iff L or R are NaN
