fhdl/decorators: make the transform logic more idiomatic
...
* the transformers work on classes and instances.
you can now do just do:
@ResetInserter()
@ClockDomainRenamer({"sys": "new"})
class Foo(Module):
pass
or:
a = ResetInserter()(FooModule())
* the old usage semantics still work
* the old DecorateModule is deprecated,
ModuleDecorator has been refactored into ModuleTransformer
(because it not only decorates things)

it's generally better to have identical code between simulations and synthesis, but here tricks inserted for simulation are clearly expected to be simplified by synthesis tools, so it's better not inserting them.

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])

in two different modules, and one of these modules is subject
to clock domain remapping. The clock domain of the port in that

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:])
