Test className() even without demangling
Run the classnametest is now run two times:
-
classnametest-demangled
: skipped if__cxa_demangle()
is missing -
classnametest-fallback
: an exit-status of 1 (resulting from failed checks expecting demangling) is still considered successfull, though anything else (e.g. segfault) will fail the test.
Closes: #160 (closed)
