A while back the entry/exit points of debugify were instrumented with conversion functions to/from non-intrinsic-form debug-info. This is the path of least resistance to incrementally converting parts of LLVM to use the new format. However, it turns out that debugify registers callbacks with the pass manager and can be fed non-intrinsic form debug-info. Thus: this patch wraps each of the four major debugify functions with the convertion utilities, and extends test coverage to a test that exposes this problem. (An alternative would be to put this code in the callback lambdas, but then it would be fighting pass manager abstractions of what type the IR has). Handily debugify has been designed to record the /meaning/ of debug-info rather than take pointers to intrinsics and the like, so the storage mechanism for debug-info is transparent to it!
