mesa,llvm,meson: Update llvm to 8.0.1 plus define and use LLVM version globally

- Add missing dependency on libedit
- Define LLVMVERSION on the same lines as GCCVERSION and other tools
- Use LLVMVERSION in mesa and meson.bbclass to get llvm version instead of
  hardcoding it
- Use llvm patches unmodified from meta-clang, helps in keeping them in
  sync
- Define PREFERRED_VERSION for llvm, llvm-native, nativesdk-llvm

-Subject: [PATCH 2/2] llvm: allow env override of exe path
-
-When using a native llvm-config from inside a sysroot, we need llvm-config to
-return the libraries, include directories, etc. from inside the sysroot rather
-than from the native sysroot. Thus provide an env override for calling
-llvm-config from a target sysroot.
-
-To let it work in multilib environment, we need to provide a knob to supply
-multilib dirname as well
