hacky proof-of-concept patch

This is a very hacky proof of concept patch.  Don't try it on
anything serious, and certainly don't try to bootstrap with it --
it'll fall over in the slightest breeze.

But it does produce:

        ldp     s3, s2, [x0]
        ldp     s0, s1, [x1]
        fadd    s1, s2, s1
        fadd    s0, s3, s0
        ret

for the original testcase.
