	PR fortran/26074
	PR fortran/25103
	* resolve.c (resolve_symbol): Extend the requirement that module
	arrays have constant bounds to those in the main program.  At the
	same time simplify the array bounds, to avoiding trapping parameter
	array references, and exclude automatic character length from main
	and modules. Rearrange resolve_symbol and resolve_derived to put as
	each flavor together, as much as is possible and move all specific
	code for flavors FL_VARIABLE, FL_PROCEDURE and FL_PARAMETER into new
	functions.
	(resolve_fl_var_and_proc, resolve_fl_variable, resolve_fl_procedure):
	New functions to do work of resolve_symbol.
	(resolve_index_expr): New function that is called from resolved_symbol
	and is extracted from resolve_charlen.
	(resolve_charlen): Call this new function.
	(resolve_fl_derived): Renamed resolve_derived to be consistent with
	the naming of the new functions for the other flavours.  Change the
	charlen checking so that the style is consistent with other similar
	checks. Add the generation of the gfc_dt_list, removed from resolve_
	symbol.
