What GPU info does the CAL function provide that OpenCL doesn't?

I am moving this response over from the Boinc Alpha list about the 7.8.1
startup, because the discussion is more appropriate here. Yes AMD has
publically switched from CAL to OpenCl a few years back, but the CAL files are
still apart of the driver. Even the new RX Vega drivers still has the files
included in them. The question is what are they using them for? I don't believe
it is to maintain backwards compatibility, because AMD is very quick at cutting
off support for anything they consider legacy. I thought that maybe they were
using them as some sort of low level access to the GPU for Opencl, and to test
this I renamed the files and restarted Boinc. Low and behold, Opencl has been
and is working correctly for over 24 hours now with out the files, so again why
are they still apart of the driver and what are they using them for? Here is a
link to a project on Github for a AMD GPU assembler and disassembler that uses
the CAL and the modifications to get it working on an RX4

I think that the problem in the Boinc detection of CAL is that it does not
properly enumerate all of the possible CAL targets.
Even if Boinc gets the enumeration correct, about the only good thing that the
CAL provides now is more information about the capabilities of the GPU. And
since no projects that have tasks that run on an AMD GPU that still use a CAL
program, the time it might take to get it working correctly might not be worth
it for just the increase in info. So in fact it might be better to just remove
the CAL detection completely from Boinc reducing its size and startup time.

With the renaming of the CAL files, Boinc correctly reports that no ATI
library is found. OpenCL is found and works, but clDeviceInfo does throw the
error about not getting the number of SIMD units, but it does. And Boinc is
warning about the Astropulse r2742.cl not being the correct size. It does this
because with the last change to the file I made, I forgot to change the file
size in the client_state file. (trying to get the Astropulse units to validate,
with the recent batch of test units on SetiBeta, I'm still getting some
inconclusives thrown, but more of them are validating now, but that's a
different problem).
