class LLVM_INTEGER_TYPE
-- Integer representation type in LLVM.

-- It represents integer types, including the built-in 1-bit. 8-bit,
-- 16-bit, 32-bit and 64-bit.

-- The underlying C++ function to get or create an IntegerType pointer is
-- "const IntegerType *IntegerType::get ( LLVMContext & C, unsigned
-- NumBits )" and is a static method and it's the primary way of
-- constructing an IntegerType. If an IntegerType with the same NumBits
-- value was previously instantiated, that instance will be returned.
-- Otherwise a new one will be created. Only one instance with a given
-- NumBits value is ever created.
