Avoid unnecessary pointer scanning in garbage collection (Bug#10780).

* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
(mark_memory): Mark Lisp_Objects only if pointers might hide in
objects, as mark_maybe_pointer will catch them otherwise.
(GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
* s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
