Add an c++ itanium demangler to llvm. This adds a copy of the demangler in libcxxabi. The code also has no dependencies on anything else in LLVM. To enforce that I added it as another library. That way a BUILD_SHARED_LIBS will fail if anyone adds an use of StringRef for example. The no llvm dependency combined with the fact that this has to build on linux, OS X and Windows required a few changes to the code. In particular: No constexpr. No alignas On OS X at least this library has only one global symbol: __ZN4llvm16itanium_demangleEPKcPcPmPi My current plan is: Commit something like this Change lld to use it Change lldb to use it as the fallback Add a few #ifdefs so that exactly the same file can be used in libcxxabi to export abi::__cxa_demangle. Once the fast demangler in lldb can handle any names this implementation can be replaced with it and we will have the one true demangler. llvm-svn: 280732

[llvm-cxxfilt] Switch command line parsing from llvm::cl to OptTable Similar to D104889. The tool is very simple and its long options are uncommon, so just drop the one-dash form in this patch. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D105605

Option
[llvm-cxxfilt] Use llvm::outs(). Simplify. This adds a dependency on Support/. As llvm-cxxfilt will grow support for options this will be needed anyway. llvm-svn: 282523

[tools] Add option to install binutils symlinks The LLVM tools can be used as a replacement for binutils, in which case it's convenient to create symlinks with the binutils names. Add support for these symlinks in the build system. As with any other llvm tool symlinks, the user can limit the installed symlinks by only adding the desired ones to `LLVM_TOOLCHAIN_TOOLS`.
