unwind-chain-inclusion

# Without this patch, the first local include of unwind.h might, with the
# __has_include_next, try to include the one from the system.
# It might be /usr/include/clang/3.4/include/unwind.h
# Because of the #ifndef __CLANG_UNWIND_H, it might never include any declaration
# from the system.
