To make the decoration manger available everywhere, and to reduce the number of times it needs to be build, I add one the IRContext. As the same time, I move code that modifies decoration instruction into the IRContext from mempass and the decoration manager. This will make it easier to keep everything up to date. This should take care of issue #928.
