[Bug fortran/20923] gfortran slow for large array constructors

And this looks like the right place for an attack:
/* Given an array constructor, determine if the constructor is
   constant or not by expanding it and making sure that all elements
   are constants.  This is a bit of a hack since something like (/ (i,
   i=1,100000000) /) will take a while as* opposed to a more clever
   function that traverses the expression tree. FIXME.  */

int
gfc_constant_ac (gfc_expr *e)
