    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 t=
ypes
    whenever the original function type and formal parameter types disagree
about
    the type of a parameter after substitution.
