Log:
  Add WITH_LLVM_CXXFILT option to install llvm-cxxfilt as c++filt

  Since elftoolchain's cxxfilt is rather far behind on features, and we
  ran into several bugs, add an option to use llvm-cxxfilt as an drop-in
  replacement.

  It supports the same options as elftoolchain cxxfilt, though it doesn't
  have support for old ARM (C++ Annotated Reference Manual, not the CPU)
  and GNU v2 manglings. But these are irrelevant in 2020.

  Note: as we already compile the required libraries as part of libllvm,
  this will not add any significant build time either.
