Currently it is not possible to use no_sanitize("coverage") to disable coverage
instrumentation.
This came up in the context of constraints for certain Linux kernel functions:

-- The current workaround on x86 is to turn calls to __sanitizer_cov_* into
nops, however, for other architectures no such support is implemented but will
be required eventually.
