[test][llvm-cxxfilt] Fix darwin build bot When committing dba420bc05ae, I missed that a darwin-specific change had been recently introduced into llvm-cxxfilt, which my change ignored and consequently broke the darwin build bot. This change fixes this issue as well as improving naming/commenting of things related to this point so that people are less likely to run into the same issue as I did.

## Show that llvm-cxxfilt can handle basic demangling for command-line inputs,
## including when they are part of a string. Note that this test uses "-n"

## (alias for --no-strip-underscore) because on darwin, the default for
## --strip-underscore is true, but false elsewhere.

[llvm-cxxfilt] Split and demangle stdin input Summary: Originally, llvm-cxxfilt would treat a line as a single mangled item to be demangled. If a mangled name appears in the middle of that string, that name would not be demangled. GNU c++filt splits and demangles every word in a string that is piped to it via stdin. Prior to this patch llvm-cxxfilt would never split strings piped to it. This patch replicates the GNU behavior and splits strings that are piped to it via stdin.

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
