-/// TypeBuilder - This provides a uniform API for looking up types
-/// known at compile time. To support cross-compilation, we define a
-/// series of tag types in the llvm::types namespace, like i<N>,
-/// ieee_float, ppc_fp128, etc. TypeBuilder<T, false> allows T to be
-/// any of these, a native C type (whose size may depend on the host
-/// compiler), or a pointer, function, or struct type built out of
-/// these. TypeBuilder<T, true> removes native C types from this set
-/// to guarantee that its result is suitable for cross-compilation.
-/// We define the primitive types, pointer types, and functions up to
-/// 5 arguments here, but to use this class with your own types,
-/// you'll need to specialize it. For example, say you want to call a
-/// function defined externally as:
-///
-/// struct MyType {
-/// int32 a;
-/// int32 *b;
-/// void *array[1]; // Intended as a flexible array.
-/// };
-/// int8 AFunction(struct MyType *value);
-///
-/// You'll want to use
-/// Function::Create(TypeBuilder<types::i<8>(MyType*), true>::get(), ...)
-/// to declare the function, but when you first try this, your compiler will
-/// complain that TypeBuilder<MyType, true>::get() doesn't exist. To fix this,
-/// write:
-///
-/// namespace llvm {
-/// template<bool xcompile> class TypeBuilder<MyType, xcompile> {
-/// public:
-/// static StructType *get(LLVMContext &Context) {
-/// // If you cache this result, be sure to cache it separately
-/// // for each LLVMContext.
-/// return StructType::get(
-/// TypeBuilder<types::i<32>, xcompile>::get(Context),
-/// TypeBuilder<types::i<32>*, xcompile>::get(Context),
-/// TypeBuilder<types::i<8>*[], xcompile>::get(Context),
-/// NULL);
-/// }
-///
-/// // You may find this a convenient place to put some constants
-/// // to help with getelementptr. They don't have any effect on
-/// // the operation of TypeBuilder.
-/// enum Fields {
-/// FIELD_A,
-/// FIELD_B,
-/// FIELD_ARRAY
-/// };
-/// }
-/// } // namespace llvm
-///
-/// TypeBuilder cannot handle recursive types or types you only know at runtime.
-/// If you try to give it a recursive type, it will deadlock, infinitely
-/// recurse, or do something similarly undesirable.

-// Define the C integral types only for TypeBuilder<T, false>.
-//
-// C integral types do not have a defined size. It would be nice to use the
-// stdint.h-defined typedefs that do have defined sizes, but we'd run into the
-// following problem:
-//
-// On an ILP32 machine, stdint.h might define:
-//
-// typedef int int32_t;
-// typedef long long int64_t;
-// typedef long size_t;
-//
-// If we defined TypeBuilder<int32_t> and TypeBuilder<int64_t>, then any use of
-// TypeBuilder<size_t> would fail. We couldn't define TypeBuilder<size_t> in
-// addition to the defined-size types because we'd get duplicate definitions on
-// platforms where stdint.h instead defines:
-//
-// typedef int int32_t;
-// typedef long long int64_t;
-// typedef int size_t;
-//
-// So we define all the primitive C types and nothing else.
