We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Similarly to Clang, the flag enables coverage instrumentation, and links
`libLLVMFuzzer.a` to the produced binary.
Additionally, this change affects the driver logic, and enables the
concurrent usage of multiple sanitizers.
With this patch different sanitizers (tsan/asan) will be enabled or
disabled on the driver level on a particular OS depending on whether
the required library is present.
The current patch only supports Darwin architectures, but Linux support
should not be hard to add.
"Sanitizer Coverage" with a new flag ``-sanitize-coverage=``. This
flag is analogous to Clang's ``-fsanitize-coverage=``.
This instrumentation currently requires ASan or TSan to be enabled
because the module pass created by ``createSanitizerCoverageModulePass()``
inserts calls into functions found in compiler-rt's "sanitizer_common".
"sanitizer_common" is not shipped as an individual library but instead
exists in several of the sanitizer runtime libraries so we have to
link with one of them to avoid linking errors.
The rationale between adding this feature is to allow experimentation
with libFuzzer which currently relies on "Sanitizer Coverage"
instrumentation.
