I think that it would be completely reasonable (maybe even, "insanely great"?) to put move constructors and assignment operators into llvm & clang if they help performance and are *optional* and ifdef'd on compiler support.

That would just mean that people with c++'11 compilers can get better build times, but that we remain compatible with older compilers.
