re PR fortran/56008 ([F03] wrong code with lhs-realloc on assignment with derived types having allocatable components)

	PR fortran/56008
	PR fortran/47517
	* trans-array.c (gfc_alloc_allocatable_for_assignment): Save
	the lhs descriptor before it is modified for reallocation. Use
	it to deallocate allocatable components in the reallocation
	block.  Nullify allocatable components for newly (re)allocated
	arrays.
