Avoid devirtualisation overhead for helper classes

      Description

      Currently there are several functions that have inline default implementations in eclhelper.hpp.  Some of them are called often (e.g., does this row filter ok in a disk read).  Because they are called over a dll boundary the devirtualisation optimization will never work, so remove the default implementations to avoid the check.
