x86, mce: export MCE severities coverage via debugfs
The MCE severity judgement code is data-driven, so code coverage tools
such as gcov can not be used for measuring coverage. Instead a dedicated
coverage mechanism is implemented. The kernel keeps track of rules
executed and reports them in debugfs.
This is useful for increasing coverage of the mce-test testsuite.
Right now it's unconditionally enabled because it's very little code.
