Try to fix CI

mostly LGTM, but some minor issue.

libcxx/include/__math/remainder.h

Nit: since the file contains modulo to, how about naming the file math_division.h instead or move the modulo to its own file.

libcxx/test/std/depr/depr.c.headers/math_h.pass.cpp
10

Why is this needed, can you mention this in the commit message?

I think moving the modules to their own file sounds good.

libcxx/test/std/depr/depr.c.headers/math_h.pass.cpp

I'll check again whether it's actually needed. This might just be a leftover from trying to fix something. (I suspect it's not actually needed)

It would be great when it's not needed. This feels a bit out of place.

@philnik Sorry for the late comment but we just noticed that our build is broken with this commit.

We do run into name collision with __math being a header guard macro defined into one of our internal headers. Can it be change to have a different name, say __math_impl or something like that?

To clarify it isn't an internal header but the system math.h header. The z/OS system headers tend to use macros like __math or __stdio for the file guard macros.
