[SCEV] Add test where result depends on order loop guards are applied.

This patch adds 2 test cases where we fail to determine a tight bound on
the backedge taken count because the ULT condition is applied before the
signed conditions. The order the conditions are applied impacts which
min/max folds are applied.
