Fortran: Auto array allocation with function dependencies [PR59104]

2024-06-20  Paul Thomas  <pault@gcc.gnu.org>

gcc/fortran
	PR fortran/59104
	* dependency.cc (dependency_fcn, gfc_function_dependency): New
	functions to detect dependency in array bounds and character
	lengths on old style function results.
	* dependency.h : Add prototype for gfc_function_dependency.
	* error.cc (error_print): Remove trailing space.
	* gfortran.h : Remove dummy_order and add fn_result_spec.
	* symbol.cc : Remove declaration of next_dummy_order..
	(gfc_set_sym_referenced): remove setting of symbol dummy order.
	* trans-array.cc (gfc_trans_auto_array_allocation): Detect
	non-dummy symbols with function dependencies and put the
	allocation at the end of the initialization code.
	* trans-decl.cc : Include dependency.h.
	(decl_order): New function that determines uses the location
	field of the symbol 'declared_at' to determine the order of two
	declarations.
	(gfc_defer_symbol_init): Call gfc_function_dependency to put
	dependent symbols in the right part of the tlink chain. Use
	the location field of the symbol declared_at to determine the
	order of declarations.
	(gfc_trans_auto_character_variable): Put character length
	initialization of dependent symbols at the end of the chain.
	* trans.cc (gfc_add_init_cleanup): Add boolean argument with
	default false that determines whther an expression is placed at
	the back or the front of the initialization chain.
	* trans.h : Update the prototype for gfc_add_init_cleanup.
