Dynamic subarray offset

[defund]

Feature request: subarrays with a dynamic starting index. Note that Jasmin already supports dynamic indexes for array access. For subarrays, the syntax might look like this:

reg u64 i;
reg ptr u8[N*M] arr;
reg ptr u8[N] sub;

...

i = 0;
while (i < N * M)
{
	sub = arr[i:N];

	...

	i += M;
}

I have a branch somewhere, let me resurrect it.

I have just rebased the branch: subarray_unknown_index. @defund I know the branch is a bit buggy, but please try it and report whether it suits your needs or if it has limitations. And please check whether it generates the right assembly. I am not confident that even this part is right.

Ping @defund. Have you tried the branch?
