Fix a pair of related issues with estimation of inequalities that involve
binary-compatible relabeling of one or both operands. examine_variable
should avoid stripping RelabelType from non-variable expressions, so that
they will continue to have the correct type; and convert_to_scalar should
just use that type and ignore the other input type. This isn't perfect
but it beats failing entirely. Per example from Michael Fuhr.
