Add the $arch-registered-target features that clang uses to disable
tests that require a registered backend, so that we can run the sancov
tests on Windows. LLVM's lit suite did not appear to have a per-test way
to do this, and I would rather not split up the sancov tests into
architecture directories.

Original commit message:
[sancov] Run sancov tests on more platforms
The only tests that need to be run on Linux are the ones that use C++
demangling. I'm assuming they will fail on Mac, since __cxa_demangle
there won't handle the non-double-underscore prefixed mangled names.

Multi-dso programs result in multiple coverage files dumped of the form
'<module_name>.<pid>.sancov'. When analyzing these coverage files it is
important to use correct corresponding object file.
This change removes the "-obj" sancov flag and lets user specify object
file names alongside coverage files. Sancov tool would match them using
<module_name> part of coverage file and short file name of the object
file.

Summary:
Using the blacklist the user can filter own unwanted functions
from all outputs. By default blacklist contains "fun:__sancov*" line.
