Subject: Initial implementation of elaboration system tasks (IEEE1800-2017
 section 20.11) This PR allows us to use $info/$warning/$error/$fatal **at
 elaboration time** within a generate block. This is very useful to stop a
 synthesis of a parametrized block when an illegal combination of parameters
 is chosen.
