Propose to replace cyclic dependency error msg

[Denis Feklushkin]

Hi!

Just want to propose to replace compiler message from:

"Cyclic dependency between module xxx and yyy"

by

"Cyclic dependency between module ctors/dtors xxx and yyy"

Several times faced with the fact that people do not understand 
that compiler talking about constructors and they try to solve 
the nonexistent problem of looped import.
