No idea about the DMD backend, but in LLVM you generally just 
declare a global of some arbitrary IR type (e.g., from a D type: 
`DtoType(dtype)`), and the resulting GlobalVariable will always 
be a pointer to that type. You define the global by setting an 
initializer. See the pretty new `{declare,define}Global()`
