Steven Wu e84468c1f1 [llvm-cxxfilt] Improve strip-underscore behavior
Summary:
For platform that uses macho format, c++filt should be stripping the
leading underscore by default. Introduce the binutil compatible "-n"
option to control strip-undercore behaivor together with the existing
"-_" option and fallback to system default if none of them are set.

Saleem Abdulrasool c8bcda2b56 llvm-cxxfilt: filter out invalid manglings
c++filt does not attempt to demangle symbols which do not match its
expected format.  This means that the symbol must start with _Z or ___Z
(block invocation function extension).  Any other symbols are returned
as is.  Note that this is different from the behaviour of __cxa_demangle
which will demangle fragments.
