[Bug c/23658] New: bogus warning for missing return value

[gdr at gcc dot gnu dot org]

The testcase below was distilled from GMP source code (thanks to TG).
Consider

  inline int foo (void){ if (1) return 0; }
  int bar () { return foo (); }

compile with "-Wall -O2 -c".  Gcc spits out

tg.c: In function 'bar':
tg.c:2: warning: control may reach end of non-void function 'foo' being inlined

which clearly is bogus as the branch is *always* taken.
