This fixes issues where passes get unregistered before llvm_shutdown is
called, and is generally cleaner and simpler.  Analysis groups up next.

convertToThreeAddress() is now responsible for updating live info as well as inserting the new MI's.

until this happens at least make sext from bool and sitofp from bool do the
right thing.

A initialized global variable cannot be extern weak. However, if a global value's initializer is itself a external weak symbol, emit the weak reference.
