    * asan.c (asan_emit_stack_protection): Force the base to align to
    appropriate bits if STRICT_ALIGNMENT.  Set shadow_mem align to
    appropriate bits if STRICT_ALIGNMENT.
    * cfgexpand.c (expand_stack_vars): Set base_align appropriately
    when asan is on.
    (expand_used_vars): Leave a space in the stack frame for alignment
    if STRICT_ALIGNMENT.
