Issue an warning when the code tries to do an implicit int -> float conversion, where the float type ha a narrower significant than the float type. The new warning is controlled by flag -Wimplicit-int-float-conversion, under -Wimplicit-float-conversion and -Wconversion. It is also silenced when c++11 narrowing warning is issued.
