Introduce -nostdlib++ flag to disable linking the C++ standard library. Projects that want to statically link their own C++ standard library currently need to pass -nostdlib or -nodefaultlibs, which also disables linking of the builtins library, -lm, and so on. Alternatively, they could use `clang` instead of `clang++`, but that already disables implicit addition of -lm on some toolchains. Add a dedicated flag -nostdlib++ that disables just linking of libc++ / libstdc++. This is analogous to -nostdinc++. https://reviews.llvm.org/D35780 llvm-svn: 308997
