5. Add named signed and unsigned comparison functions and remove the

6. Remove operator&& and operator|| but provide a getBoolValue function which
converts to bool as comparison against 0. This allows the normal && and
|| operators to be used as if (X.getBoolValue() && Y.getBoolValue())
Note: this still doesn't function 100% yet. I'm working on the bugs now.

Instead, the stat info is printed when llvm_shutdown() is called.
