[PATCH] D112748: [release] Use the Bootstrapping build for building LLVM releases

Instead of using the (now deprecated) Projects build for libcxx, libcxxabi
and libunwind, this patch uses the Bootstrapping build. This implies that
Clang will be built from scratch, and then the runtimes will be built using
that just-built Clang instead of the system compiler. This is the correct
way of assembling a toolchain, since we don't want to ship runtimes that
were built with a non-Clang compiler (or a potentially older Clang).
