3223. lerp should not add the "sufficient additional overloads"

Discussion:

It seems that lerp can't give a sensible answer for integer inputs. It's new machinery, not the legacy C stuff extended with extra overloads.

I would prefer to fix this by explicitly annotating the functions that are supposed to get additional overloads because we keep getting this wrong, but we could also exempt lerp in 29.7.1 [cmath.syn] p2.

Priority to 2 after discussion on the reflector.

Resolved by the application of P1467R9. It's now clear that lerp should have "sufficient additional overloads".
