This check is to enforce C++ core guideline C.49 while the modernize check 
enforces guideline C.48. The two must be synchronized, and I think that this 
new check should do that: for initializations that should  be done using 
in-class initializers according to the other checker this checker must suggest 
the same. For the rest we should suggest member initializers in the constructor.
