Switch to LLVM 7 toolchain and start work on the following:
[ ] ~Use LLVM linker rather than being tied to clang~ (Difficult as we don't emit object code yet. Pluggable linkers is on the roadmap though. (link.exe for windows, Clang, Gold linker etc.)
[x] Use the correct target machine for the current platform when emitting code
[x] Switch to failure for error modelling.
[x] Add Optimisation flags and use them to trigger optimisation passes in the compiler
[ ] ~Rust 2018 edition??~ Best to wait for 2018 to make it to stable rust first. Updated to have a version specified so we are "edition ready" at least.
