LLVM doesn't install "CheckAtomic" cmake file, so add it locally.
Bump required CMake version to 3.4.3 (sync with the master CMakeLists.txt)
This fixes build on NetBSD.

I think it is a bad idea to duplicate the CheckAtomic.cmake file from LLVM as the 2 copy will diverge over time and cause extra maintenance cost. What do you think about trying to change LLVM to install this file instead of duplicating it into LLDB?
I agree with Tamas that this should somehow be handled in a different way. llvm already installs a bunch of cmake files. I think we should figure out a way to get the things we need installed alongside that, so we can just reuse them from there.
