Run runs the language specific analyzers on the code given packages and source info.

- opt-level=3 (Use the highest optimisation level (default with --release)) - debuginfo=1 (Include DWARF debug info which is extracted to find which funcs are called) - embed-bitcode=yes (Required to enable LTO) - lto (Enable full link time optimisation, this allows unused dynamic dispatch calls to be optimised out) - codegen-units=1 (Build everything in one codegen unit, increases build time but enables more optimisations and make libraries only generate one object file).
