Could that be done by splitting the diagnostic into two?  When there is no
implicit conversion sequence for an argument which is an overload set print one
message (like clang's "no overload of 'f'") and otherwise print the existing
message.

I prefer G++'s error for the second candidate, the process that fails is
template argument deduction, not template argument inference.
