So, these headers need the ability to do some potentially ugly hacks. I have
added an extra field to the `PublicAPI` called `ExtraDefn`, which is currently a
simple string that we can use to inject some special-case handling for the
wrapper headers. In this case, we needed to define the `__atexithander_t` type
for the `atexit` function. In general this can be used as a general purpose shim
to address edge cases.

It's not pretty, but as I've stated I think this is the only sound solution to
this problem short of fully implementing the LLVM C library for both the host
and device.

The generated headers still pass the test suite as internally nothing has
changed. Externally, I can now safely include these headers inside OpenMP
without the prior errors.
