1. Abundance of caution / taking baby steos. No on had yet complained about how LLVM/Clang work yet pre the name collision.

2. I was planning on not trying to hack in compiler-rt using `llvm/cmake/modules` until `HandleOutOfTreeLLVM` there was fixed to handle that for us more cleanly. Conversely, compiler-rt can already use `cmake/Modules` just fine.
