Like m_Specific(), but works if the specific value to match is determined as part of the same match() expression.

For example: m_Add(m_Value(X), m_Specific(X)) is incorrect, because m_Specific() will bind X before the pattern match starts. m_Add(m_Value(X), m_Deferred(X)) is correct, and will check against whichever value m_Value(X) populated.

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 'maximum' semantics. In the presence of 'NaN' we have to preserve the original select(fcmp(ogt/ge, L, R), L, R) semantics matched by this predicate.

Match an 'unordered' floating point maximum 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 'maximum' semantics. In the presence of 'NaN' we have to preserve the original select(fcmp(ugt/ge, L, R), L, R) semantics matched by this predicate.

                    max(L, R)  iff L and R are not NaN
