Research direction
Start by locating the DAG implementation of getIdentityElement and isIdentityElement and the definitions of ISD::PSEUDO_FMIN and ISD::PSEUDO_FMAX. Determine how these pseudo-operations should be handled and identify the relevant compiler tests; done means both methods handle the two operations with passing coverage.
