Bridging Minix & llvm-apps repos for instrumentating Minix

Browse Source 
Allows instrumentation of Minix components using LLVM passes from
"llvm-apps" repository

In addition, the change does the following:
 1. Move releasetools/generate_gold_plugin.sh to minix/llvm
 2. Move external/bsd/llvm/passes to minix/llvm/passes
 3. libLTO.so, LLVMgold.so and WeakAliasModuleOverride.so files
    now get installed in minix/llvm/bin
