bac62a32a9 Make memory ports part of specials 
This is needed to handle cases where a single memory has ports
in two different modules, and one of these modules is subject
to clock domain remapping. The clock domain of the port in that
module only must be remapped.

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:])
