sys-devel/llvm: musl & default runtime lib switches, #589352
- add support for building llvm against musl - enable clang to build binaries against musl - introduce USE flag "sanitize" to control the building of compiler-rt's sanitizers (they cause problem on musl) - be able to override default values of -stdlib and -rtlib for clang * USE="default-libcxx" implies -stdlib=libc++ (originally libstdc++) * USE="default-compiler-rt" implies -rtlib=compiler-rt (originally libgcc)

4. LLVM does not imply things that you would expect from a high-level virtual machine. It does not require garbage collection or run-time code generation (In fact, LLVM makes a great static compiler!). Note that optional LLVM components can be used to build high-level virtual machines and other systems that need these services.</longdescription>
