Implement unconditional unswitching of 'trivial' loops, those loops that contain

Simplify the loop-unswitch pass, by not even trying to unswitch loops with
...
uses of loop values outside the loop. We need loop-closed SSA form to do
this right, or to use SSA rewriting if we really care.

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.
