2015-06-15  Andre Vehreschild  <vehre@gmx.de>

	PR fortran/44672
	PR fortran/45440
	PR fortran/57307
	* gfortran.h: Extend gfc_code.ext.alloc to carry a
	flag indicating that the array specification has to be
	taken from expr3.
	* resolve.c (resolve_allocate_expr): Add F2008 notify
	and flag indicating source driven array spec.
	(resolve_allocate_deallocate): Check for source driven
	array spec, when array to allocate has no explicit
	array spec.
	* trans-array.c (gfc_array_init_size): Get lower and
	upper bound from a tree array descriptor, except when
	the source expression is an array-constructor which is
	fixed to be one-based.
	(retrieve_last_ref): Extracted from gfc_array_allocate().
	(gfc_array_allocate): Enable allocate(array, source=
	array_expression) as specified by F2008:C633.
	(gfc_conv_expr_descriptor): Add class tree expression
	into the saved descriptor for class arrays.
	* trans-array.h: Add temporary array descriptor to
	gfc_array_allocate ().
	* trans-expr.c (gfc_conv_procedure_call): Special handling
	for _copy() routine translation, that comes without an
	interface. Third and fourth argument are now passed by value.
	* trans-stmt.c (gfc_trans_allocate): Get expr3 array
	descriptor for temporary arrays to allow allocate(array,
	source = array_expression) for array without array
	specification.
