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

Demangle
[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
