 `boost::units::detail::demangle` does not demangle names on clang with
 libc++ even when `cxxabi.h` is available.
 Attached a patch to add `cxxabi.h` detection code for clang.
 This allows `boost::units::detail::demangle` to use `abi::__cxa_demangle`
 on clang when `cxxabi.h` is available.

 The patch uses clang's `__has_include` macro to detect `cxxabi.h`.
 This macro checks the existence of a header file.
 For reference, here is the link to `__has_include` documentation:
 http://clang.llvm.org/docs/LanguageExtensions.html#has_include
