Jakub Jelinek 21ea4922ac re PR fortran/49540 (Memory-hog with large DATA stmt)
PR fortran/49540
	* gfortran.h (gfc_constructor): Add repeat field.
	* trans-array.c (gfc_conv_array_initializer): Handle repeat > 1.
	* array.c (current_expand): Add repeat field.
	(expand_constructor): Copy repeat.
	* constructor.c (node_free, node_copy, gfc_constructor_get,
	gfc_constructor_lookup): Handle repeat field.
	(gfc_constructor_lookup_next, gfc_constructor_remove): New functions.
	* data.h (gfc_assign_data_value): Add mpz_t * argument.
	(gfc_assign_data_value_range): Removed.
	* constructor.h (gfc_constructor_advance): Removed.
	(gfc_constructor_lookup_next, gfc_constructor_remove): New prototypes.
	* data.c (gfc_assign_data_value): Add REPEAT argument, handle it and
	also handle overwriting a range with a single entry.
	(gfc_assign_data_value_range): Removed.
	* resolve.c (check_data_variable): Adjust gfc_assign_data_value
	call.  Use gfc_assign_data_value instead of
	gfc_assign_data_value_expr.

	* gfortran.dg/pr49540-1.f90: New test.
	* gfortran.dg/pr49540-2.f90: New test.
