re PR fortran/30723 (Freeing memory doesn't need to call a library function)

       PR fortran/30723

	* trans.h (gfor_fndecl_internal_malloc, gfor_fndecl_internal_malloc64,
	gfor_fndecl_internal_free): Remove prototypes.
	(gfor_fndecl_os_error, gfc_call_free, gfc_call_malloc): Add prototypes.
	* trans.c (gfc_call_malloc, gfc_call_free): New functions.
	* f95-lang.c (gfc_init_builtin_functions): Add __builtin_free
	and __builtin_malloc builtins.
	* trans-decl.c (gfor_fndecl_internal_malloc,
	gfor_fndecl_internal_malloc64, gfor_fndecl_internal_free): Remove.
	(gfor_fndecl_os_error): Add.
	(gfc_build_builtin_function_decls): Don't create internal_malloc,
	internal_malloc64 and internal_free library function declaration.
	Create os_error library call function declaration.
	* trans-array.c (gfc_trans_allocate_array_storage,
	gfc_trans_auto_array_allocation, gfc_trans_dummy_array_bias,
	gfc_conv_array_parameter, gfc_duplicate_allocatable): Use
	gfc_call_malloc and gfc_call_free instead of building calls to
	internal_malloc and internal_free.
	* trans-expr.c (gfc_conv_string_tmp): Likewise.
	* trans-stmt.c (gfc_do_allocate, gfc_trans_assign_need_temp,
	gfc_trans_pointer_assign_need_temp, gfc_trans_forall_1,
	gfc_trans_where_2: Likewise.
	* trans-intrinsic.c (gfc_conv_intrinsic_ctime,
	gfc_conv_intrinsic_fdate, gfc_conv_intrinsic_ttynam,
	gfc_conv_intrinsic_array_transfer, gfc_conv_intrinsic_trim): Likewise.

	* runtime/memory.c (internal_malloc, internal_malloc64,
	internal_free): Remove.
	* runtime/error.c (os_error): Export function.
	* intrinsics/move_alloc.c: Include stdlib.h.
	(move_alloc): Call free instead of internal_free.
	(move_alloc_c): Wrap long lines.
	* libgfortran.h (os_error): Export prototype.
	(internal_free): Remove prototype.
	* gfortran.map (GFORTRAN_1.0): Remove _gfortran_internal_free,
	_gfortran_internal_malloc and _gfortran_internal_malloc64.
	Add _gfortran_os_error.
