72579a6129 Add support for negative slice indices 
In python a negative indices usually mean start counting from the right side.
I.e. if the index is negative is acutal index used is len(l) + i. E.g. l[-2]
equals l[len(l)-2].

Being able to specify an index this way also comes in handy for migen slices in
some cases. E.g. the following snippet can be implement to shift an abitrary
length register n bits to the right:
	reg.eq(Cat(Replicate(0, n), reg[-n:])
