[Bug c++/41830] New: Missing "warning: control reaches end of non-void function" in -O2

[grxnprzn at gmx dot net]

Example: 

  class Bug {};
  const Bug bug() {}

compile with "-Wreturn-type -O1": no warning
compile with "-Wreturn-type -O2": no warning
compile with "-Wreturn-type -O3": warning printed

If I read the documentation correctly, -Wreturn type should work with or
without optimizing.
