The only difference between our wrappers and the plain LLVM functions is that our wrappers take an extra volatile argument. But we can easily just set the volatile flag on the LLVM IR instructions after creating them using LLVMSetVolatile.

The only difference between our wrappers and the plain LLVM functions
is that our wrappers take an extra `volatile` argument. But we can easily
just set the `volatile` flag on the LLVM IR instructions after creating
them using `LLVMSetVolatile`.
