David Carne 16ebe41028 fhdl/tools: BUGFIX: fix group_by_target grouping
group_by_target does not properly combine target groups if statements
are presented in the order:

 ({A}, statement1)
 ({B}, statement2)
 ({A, B}, statement3)

which returns groups:

 ({A, B}, [statement1, statement3])
 ({B}, [statement2])

This patch fixes group_by_target such that the resulting group is:

 ({A, B}, [statement1, statement2, statement3])

module only must be remapped.

Lars-Peter Clausen dea4674922 Allow SimActors to produce/consume a constant stream of tokens
Currently a SimActor requires one clock period to recover from consuming or
producing a token. ack/stb are deasserted in the cycle where the token is
consumed/produced and only re-asserted in the next cycle. This patch updates the
code to keep the control signals asserted if the actor is able to produce or
consume a token in the next cycle.

The patch also sets 'initialize' attribute on the simulation method, this will
make sure that the control and data signals will be ready right on the first
clock cycle.

Lars-Peter Clausen 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:])
