kernel: call hierarchy for abstract modules automatically.

Browse source 
Whenever there are abstract modules in the netlist and the pass does not
declare that it supports them, call `hierarchy -auto-top` or `hierarchy`
(depending on whether there is a module marked `top`) to instantiate
them first. This makes several CLI workflows much more usable, including
one as basic as:

    $ yosys file.v -o file.il
