    c++: Function type and parameter type disagreements [PR92010]

    This resolves parts of Core issues 1001/1322 by rebuilding the function
type
    of an instantiated function template in terms of its formal parameter types
    whenever the original function type and formal parameter types disagree
about
    the type of a parameter after substitution.
