Fortran : ICE on invalid code PR95398
The CLASS_DATA macro is used to shorten the code accessing the derived
components of an expressions type specification. If the type is not
BT_CLASS the derived pointer is NULL resulting in an ICE. To avoid
dereferencing a NULL pointer the type should be BT_CLASS.

* resolve.c (resolve_select_type): Add check for BT_CLASS
type before using the CLASS_DATA macro which will have a
NULL pointer to derive components if it isn't BT_CLASS.
