[RFC][SVE] Supporting SIMD instruction sets with variable vector lengths
...nce like {start, op, step}. In
C++'s iota (AFAICS), the step is always 1.
Anyway, I don't mind any name, really. Whatever is more mnemonic.

Once stepvetor (or iota) becomes a proper IR instruction, I'd like to
see this restricted to inlined syntax. The sequence { step*vec +
offset } only makes sense in the sc...
