Minotaurus and LLVM

Julia demo can be compiled through LLVM now. We tested the new LLVM - Minotaurus interface today successfully.

Basic Minotaurus functionality, as code generation, and host code synthesis is enhanced now to use LLVM (in addition of GCC). Julia demo needs only the fundamental features of Minotaurus (that's why it is more than one year old code), so it already runs in this early phase of LLVM integration.

Full functionality is in progress, in a few weeks we expect Curtain demo to run as well. LLVM is significantly better documented system, so the progress is faster not just because we already done the same tasks with GCC.
