[PATCH] D53538: NFC: Reorganize the demangler a bit

With this patch, the copies of the files ItaniumDemangle.h, StringView.h, and Utility.h are kept byte-for-byte in sync between libcxxabi and llvm. All differences (namespaces, fallthrough, and unreachable macros) are defined in each copies' DemanglerConfig.h. This patch also adds a script to copy changes from libcxxabi (cp-to-llvm.sh), and a README.txt explaining the situation.

Thanks for taking a look!
