zpu: a little less Frankenstein in the stackpass
Plan is to make the stack pass work in a very simple way.
For LHS registers a new stockslot will be created only once, RHS registers will use previous created stackslots.
So
r0 = load ...
r1 = load ...
r2 = add r1,r0
will be
[sp0] = load ...
[sp1] = load ...
[sp2] = add [sp1],[sp0]
