alloc_size, yeah, unconditionally, on the other side it is used just
by __builtin_object_size which is used (usually) only for
-D_FORTIFY_SOURCE*.
I wanted to separate alloc_size attribute issue from malloc (where I'd
surely prefer also adding it by default and having an option to disable it
for weird C++ sources), because with -D_FORTIFY_SOURCE* or
__builtin_object_size one has to request it specially and/or use extensions
and thus not be that tighly bound by the standard.
