/* Only test there's no tagging done when not at -O0.  Without optimisation
   the compiler creates a bunch of other variables on the stack other than the
   vararray/alloca object.
   We also avoid checking when using -flto, since with LTO the compiler can
   recognise the vararray is only used with one size and that size is known at
   compile time -- when the compiler recognises that it instead creates a
   static array, which gets tagged as is expected but not as the test expects.
