Remove TypeBuilder.h, and fix the few locations using it.

Browse Source 
This shortcut mechanism for creating types was added 10 years ago, but
has seen almost no uptake since then, neither internally nor in
external projects.

The very small number of characters saved by using it does not seem
worth the mental overhead of an additional type-creation API, so,
delete it.

How to Create Types
-------------------
In generating IR, you may need some complex types. If you know these types
statically, you can use ``TypeBuilder<...>::get()``, defined in
``llvm/Support/TypeBuilder.h``, to retrieve them. ``TypeBuilder`` has two forms
depending on whether you're building types for cross-compilation or native
library use. ``TypeBuilder<T, true>`` requires that ``T`` be independent of the
host environment, meaning that it's built out of types from the ``llvm::types``
(`doxygen <http://llvm.org/doxygen/namespacellvm_1_1types.html>`__) namespace
and pointers, functions, arrays, etc. built of those. ``TypeBuilder<T, false>``
additionally allows native C types whose size may depend on the host compiler.
For example,
.. code-block:: c++
FunctionType *ft = TypeBuilder<types::i<8>(types::i<32>*), true>::get();
is easier to read and write than the equivalent
.. code-block:: c++
std::vector<const Type*> params;
params.push_back(PointerType::getUnqual(Type::Int32Ty));
FunctionType *ft = FunctionType::get(Type::Int8Ty, params, false);
See the `class comment
<http://llvm.org/doxygen/TypeBuilder_8h_source.html#l00001>`_ for more details.

/// 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:
///
/// \code{.cpp}
///
/// struct MyType {
/// int32 a;
/// int32 *b;
/// void *array[1]; // Intended as a flexible array.
/// };
/// int8 AFunction(struct MyType *value);
///
/// \endcode
///
/// 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:
///
/// \code{.cpp}
///
/// 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),
