test case for nested anonymous struct constructor compiler bug

The attached test program causes an assert "Invalid GetElementPtrInst indices
for type!" when generating the constructor.  Top of stack is:

llvm::checkGEPType()
llvm::GetElementPtrInst::Create()
llvm::GetElementPtrInst::CreateInBounds()
llvm::IRBuilder<1,llvm::ConstantFolder,llvm::IRBuilderDefaultInserter<1>
>::CreateConstInBoundsGEP2_32()
llvm::IRBuilder<1,llvm::ConstantFolder,llvm::IRBuilderDefaultInserter<1>
>::CreateStructGEP()
clang::CodeGen::CodeGenFunction::EmitLValueForField()

Full output attached and test program.
