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/.

The CodeEmitterGenerator used to consider ANY uninitialized field as being an

operand (unless it's annul or predict). Now we only consider fields to be
operands if they are uninitialized AND used in the "Inst" field.
