455a7bc6c8 lib.memory: Allow setting Memory.init. 
The `init` property is already mutable, so this adds no actual new
functionality, just convenience.

a586df89ad lib.wiring.connect: diagnostic when no connection made. 
If a connect() call results in no connections being made, and it's
because there were no outputs specified at all, issue an error.

09029cdd91 hdl._ir: remember origins of a fragment during elaboration. 
This isn't expected to result in a significant increase in memory use,
so for now it's enabled by default. Elaboration chains where it is not
desired to preserve origins can delete the `origins` attribute from
the fragment and nothing will be stored.

The interface `Fragment.origins` remains private, as is the rest of
the `Fragment` interface (including itself), but it enables certain
codebases that currently use a much more invasive technique to rely on
reading a single private field.

c40cfc9fb5 lib.enum: honor enum.nonmember. 
Use _EnumDict._member_names to determine which members to consider.
This way we don't need to redo sunder/dunder checks, and `nonmember`s
(introduced in py3.11) are correctly excluded.

This is a defacto public API, given it remains usable from py3.8
until py3.12 inclusive.  (_member_names changes from a list to a
keys-only dict for performance reasons in py3.11, but they iterate the
same.) In current Python main (i.e. what will most likely be 3.13), a
"member_names" property is added which returns those keys.

6f44438e58 hdl._ir,hdl._nir,back.rtlil: new intermediate representation. 
The new intermediate representation will enable global analyses
on Amaranth code without lowering it to another representation
such as RTLIL.

This commit also changes the RTLIL builder to use the new IR.
