I didn't say anything about nested submodules. I was imagining the
LLVM repo being the top level repository with submodules for

projects/libcxx
projects/libcxxabi
projects/compiler-rt
tools/clang
tools/lldb

etc..

There's no nesting of submodules here. This assumes an in source tree
nesting of projects which perhaps is something we shouldn't do given
that the projects can also be built outside the source tree.

However I should say given previous experience with submodules I am a
little bit wary using them because of the problems caused by
developers not using them properly and breaking stuff.

I like the sounds of Mehdi's proposal of an automated integration
repository although I would need to look at the details a little
closer.
