Get the LLVM type corresponding to a Rust type, i.e. rustc::ty::Ty. The pointee type of the pointer in PlaceRef is always this type. For sized types, it is also the right LLVM type for an alloca containing a value of that type, and most immediates (except bool). Unsized types, however, are represented by a "minimal unit", e.g. [T] becomes T, while str and Trait turn into i8 - this is useful for indexing slices, as &[T]'s data pointer is T*. If the type is an unsized struct, the regular layout is generated, with the inner-most trailing unsized field using the "minimal unit" of that field's type - this is useful for taking the address of that field and ensuring the struct has the right alignment.
