re PR fortran/55901 ([OOP] type is (character(len=*)) misinterpreted as array)

	PR fortran/55901
	* primary.c (gfc_match_varspec): Exclude dangling associate-
	names with dimension 0 from being counted as arrays.
	* resolve.c (resolve_assoc_var): Sub-strings are permissible
	for associate-names, so exclude characters from the test for
	misuse as arrays.
	* trans-decl.c (gfc_get_symbol_decl): Associate-names can use
	the hidden string length variable of their associated target.
	Signal this by setting 'length' to a constant, if the decl for
	the string length is a variable.
