SSE is now unconditionally enabled any where and most of math.h is now
actually implemented. using __builtin_<func> lead to many hangs where
the builtin function would just call itself.
userspace programs are now in userspace/programs
userspace tests are now in userspace/tests
This makes listing userspace projects much cleaner. Libraries were
already separated to their own directory, so other programs should also.
