Also move the spin wait to check for pending IPI sends to the start of

right after it. It is enough to make sure there are not multiple IPIs
being sent at the same time.

Kernel: Fix sse state saving
...
This was broken when I added SMP support. This patch makes sse kind of
dumb as it is saved and restored on every interrupt, but now it at least
works properly... I'll have to look into how sse can get optimized
nicely with SMP. Simple way would be pinning each thread to a specific
processor and doing pretty much what I had before, but sse thread saved
in processor rather than static global.
