#14 For-Loops with negative Increment

[Thomas Traber]

converts to

> for (i=(4 - 1); i<0; i=i+(-1)) begin
> mem[i] <= mem[(i - 1)];
> end

but the while term should be i>0.

Given the existence of 'downrange' it's probably not worthwhile to support negative steps. So I propose to flag an error instead. Moreover, for VHDL, steps other than 1 can't be supported anyway (because for-loops are done differently in VHDL). So steps other than 1 are flagged as error by the VHDL convertor.

Implemented in 0.6dev7.
