Clang crashes when calling getLLVMLinkageVarDefinition() in
EmitAliasDefinition() when compiling this testcase:
enum a_type { a , b, c};
typedef enum a_type b_type;
void foo(b_type x, enum a_type y){}
void bar(b_type x, enum b_type y) __attribute__ ((alias ("foo")));
DeclTy is not set because of "enum b_type" is incomplete type. So calling
getLLVMLinkageVarDefinition(cast<VarDecl>(GD.getDecl()),..) triggered an assert
because GD.getDecl() is FunctionDecl.
