static boolean overlapsLeft(Varnode left, Varnode right) {

Check for overlap when one varnode is known to be to the left of the other.

@param left the left varnode (having lower address)
@param right the right varnode (having higher address)
@return true if they overlap (not counting abutting), false otherwise.
