[PATCH] simplify_vector_constructor: Rename the second elt to elem

[H.J. Lu]

simplify_vector_constructor has

  constructor_elt *elt;
...
  FOR_EACH_VEC_SAFE_ELT (CONSTRUCTOR_ELTS (op), i, elt)
    {
      ...
      unsigned int elt;
      ...
    }

This patch renames the second elt to elem to avoid shadowing the first
elt.

        * tree-ssa-forwprop.c (simplify_vector_constructor): Rename the
        second elt to elem to avoid shadowing the first elt.
