Subject: [PATCH] Reduce the number of components initialized for LLGS further.

In http://reviews.llvm.org/D7880 the initialization for LLGS was separated out so that LLGS could initialize only the components it needs to. This further reduces the set of components initialized for LLGS.

Differential Revision: http://reviews.llvm.org/D8112
