Now that ConstantBool::True/False are gone, we can modify Type.cpp to
eliminate its static dtors, without having code that depends on order of initialization. Eliminate static ctors/dtors from Type.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30667 91177308-0d34-0410-b5e6-96231b3b80d8
