> Ah, I see. But note that you're now not supporting "use-soft-float" at all (which I think is fine at this step!), so you should update all tests to no longer use "use-soft-float".

Done. 
All llc invocations use -mattr=soft-float instead of relying on the function attributes, as must be done.

Addded a new test systemz-float-02.c to check that -msoft-float actually works all the way to assembly output. The type v4si using vector_size() gives a different output compared to gcc, so I guess this is implementation defined?

See inline comments.
