* loop-iv.c (simplify_using_condition): A condition of the form
(EQ REG CONST) can be used to simply make a substitution.
(simplify_using_initial_values): Keep track of conditions we have seen
and keep using them to simplify new expressions, while applying the
same substitutions to them as to the expression.
