I will add comments of what problems each test detects.

Each C file contains only one single test and can be built with one command,
e.g. "gcc xsave_check_exec.c", or as part of the whole selftest.

I am hoping that, should any test fail, one can easily modify the test to find
out why.

Yes, I will move set_ymm() to a header file.
