[PATCH] Fix PR12281: not emiting function which is static and marked as inline

[Andrew Pinski]

In the Darwin's back-end, it sets TREE_SYMBOL_REFERENCED instead of 
calling
mark_referenced which is needed for because of call-graph-unit needs to 
be notified
that the function is used.

The testcase which fails with no unit-at-a-time (derived from 
cppcharset.c):

static void f(void);
void g(void (*x) (void)){x();}
static inline void f(void){}
void h(){g(f);}
int main(){h();return 0;}

Thanks,
Andrew Pinski


ChangeLog:

	* config/darwin.c (machopic_validate_stub_or_non_lazy_ptr): Call 
mark_referenced
	instead of setting TREE_SYMBOL_REFERENCED.
