Hi Yonggang,

After discussion, we decided not to do this.  The bulk of libcxxrt is an older demangler (that doesn't support C++'0x) that I think they're planning to drop.  The rest of the code is relatively minor stuff like implementation of std::bad_alloc and a few other glue things that should be straight-forward to implement in libc++abi.  Since adding an external dependency complicates the licensing and distribution model, we're prefer to keep the LLVM libc++abi independent of libcxxrt.
