+/// at a specific iterator location in a block.
+///
+/// Note that the builder does not expose the full generality of LLVM
+/// instructions. For example, it cannot be used to create instructions with
+/// arbitrary names (specifically, names with nul characters in them) - It only
+/// supports nul-terminated C strings. For fully generic names, use
+/// I->setName(). For access to extra instruction properties, use the mutators
+/// (e.g. setVolatile) on the instructions after they have been created.
