[Bug fortran/37173] New: Check whether intrinsic assignment between character kind=1 / 4 is allowed

The Reply to the comments to the Fortran 2008 Candidate Draft,
http://www.j3-fortran.org/doc/year/08/08-272.html, contains:

> Unfortunately, the premise that intrinsic assignement between character 
> variables of different kind is allowed is wrong. See table 7.10 on page 152 
> of the draft: "Type conformance for the intrinsic assignment". Character 
> assignments are only allowed for "the same kind type parameter". J3 believes 
> the mapping between characters of different kind is difficult to define. 
> Consequently, J3 declines to make this addition.

If I understand the reply correctly, the following is invalid:

   character(kind=1) :: str = 4_'Hello'

We should check and reject it with -std=f* if it turns out to be invalid.
