-/// LLVMBuilder - This provides a uniform API for creating instructions and
-/// inserting them into a basic block: either at the end of a BasicBlock, or
-/// 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.
