Actually, there can be such functions; users can declare a function with
__attribute__((constructor)) and then call it normally.  But, there are
probably no DECL_ARTIFICIAL functions that are both static constructors
and called normally.  I think it would be best to put the always_inline
attribute only on the compiler-generated routines, at the time they are
created, rather than try to deduce it after the fact.

This is really not a big deal; I'm not trying to make work for you.
It's just a bit of unnecessary bloat at -O0.
