lib.fifo: remove SyncFIFO.replace.
...
This obscure functionality was likely only ever used in old MiSoC
code, and doesn't justify the added complexity. It was also not
provided (and could not be reasonably provided) in SyncFIFOBuffered,
which made its utility extremely marginal.

hdl.mem: use read_port(domain="comb") for asynchronous read ports.
...
This avoids the absurdity of the combination of arguments that is
read_port(domain="sync", synchronous=True).
Fixes #116 .

Clean up imports.
...
This commit:
* moves lists of universally useful imports from `nmigen` to
`nmigen.hdl` and `nmigen.lib`, reimporting them in `nmigen`;
* replaces lots of imports from individual parts of `nmigen.hdl`
with a star import from `nmigen.hdl`;
* replaces imports in tests with what we expect downstream code
to use;
* adds some missing imports in `nmigen.formal`.

hdl.ir: detect elaboratables that are created but not used.
...
Requres every elaboratable to inherit from Elaboratable, but still
accepts ones that do not, with a warning.
Fixes #3 .

lib.fifo: use memory in the FIFO model.

This is unfortunately more complicated, but results in a much faster
proof.

lib.fifo: use model equivalence to simplify formal specification.

This is unfortunately slow, and should probably be using theory
of arrays.
