better patch

A more consistent approach.. rather than directly call relation_intersect()
from multiple places, add the floating point fix to value_relation::intersect
and always go through that.

This will cause the normal oracle and the path oracle to both make the previous
adjustment to intersect for floating point operations.   untested, running
tests now.
