hand-written assembly

+boost/smart_ptr/detail/sp_counted_base_gcc_mips.hpp
+contains hand-written MIPS assembly, which is not compatible
+with the MIPS16e instruction set.
+
+By not using this file in MIPS16e mode, we fallback to using
+g++ 4.1+ __sync intrinsics (__sync_fetch_and_add() and
+__sync_val_compare_and_swap()) which are working fine.
