[Bug c/38037] false uninitialized warnings when using a pointer as a guard

Same happens if I use int instead of a pointer:
/* testcase */
/* gcc -O2 -Wall -c foo.c */
int get(void);
int use(int);
void foo(int bar)
{
        int foobar;

        if(!bar)
                foobar = get();

        if(use(bar))
                return;

        if(!bar)
                use(foobar);
}
