Suppress sanitizer errors about pointer arithmetic in a few places

We perform weird pointer arithmetic due to the layout of Lisp_Objects
holding symbols.  ASan/UBSan warns about that (Bug#42530).  Suppress
the warnings by performing the arithmetic on integer types and casting
back to pointers.

* src/alloc.c (mark_maybe_object, mark_memory): Temporarily cast
pointer to 'intptr_t'.
