Dinakar and I fixed a bug where we were trying to get the initializer of
an external constant. Since external constants don't have initializers, we were failing on an assert() call in llvm/GlobalVariable.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7193 91177308-0d34-0410-b5e6-96231b3b80d8
