Gaussian elimination

How to express something like Gaussian elimination in the stream
language? It probably requires the use of a double buffering scheme to
eliminate the in-place approach.

However, it might be possible to just flatten all the computations
into SSA form, and let the compiler decide.  Most practical matrices
are going to be small, so it might actually make a lot of sense to do

Trouble there is pivoting..  But let's assume condition is good.
