Compilers normally don't check for missing return statements because
it's impossible to do in the general case.

Consider

int f() {
  g();
}

in the case where g() never returns normally (i.e., it terminates
execution or throws an exception).  Warning about f would be bad in
those cases, but failing to warn if g() ever does return is bad too,
and adding runtime checks is also bad (as it adds overhead).
