Module llvm

Compilation of native dependencies like LLVM.

Native projects like LLVM unfortunately aren’t suited just yet for compilation in build scripts that Cargo has. This is because the compilation takes a very long time but also because we don’t want to compile LLVM 3 times as part of a normal bootstrap (we want it cached).

LLVM and compiler-rt are essentially just wired up to everything else to ensure that they’re always in place if needed.
