[Bug rtl-optimization/17544] [4.0 Regression] incorrect -Wunreachable-code warning for reachable code following a do statement

Confirmed, a regression on mainline. Simplified testcase:

----------------------------
int main (void)    // 1
{                  // 2
  return 0;        // 3
}                  // 4
----------------------------
17544.cc: In function `int main()':
17544.cc:4: warning: will never be executed

The warning is probably on the implicit return which is put at the end of the 
definition of main by the compiler (main is allowed to not have an explicit 
return statement).
