MFC r367304:
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.

MFC r367712:
Ensure make delete-old does not unlink the llvm-cxxfilt and its manpage, after r367304 and r367324, when WITH_LLVM_CXXFILT is enabled.
