Bug 1314762 - move #includes of system-y headers out of anonymous namespace in SSE.cpp; r=erahm

#include'ing system headers inside anonymous namespaces seems to work
OK with GCC and MSVC, but it does not work well with clang-cl in some
compilation modes.  Moving them out of the anonymous namespace makes
everybody happy.
