RFR: JDK-8181298: Assertion failure in com.sun.tools.javac.comp.Modules

[Jan Lahoda]

Hi,

The ct.sym building needs to read existing module-infos, to properly 
detect transitive dependencies. But the target does not depend on all 
module-infos being generated, which may in turn lead to problems with 
incomplete module graph.

So, the proposed patch is to add the dependency on all generated 
module-infos. javac should crash this way even in a presence of 
incomplete module graph, this will be fixed under a separate ticket.

The cause was found and patch is by Erik.
