hdl.ast: add an explicit Shape class, included in prelude.
...
Shapes have long been a part of nMigen, but represented using tuples.
This commit adds a Shape class (using namedtuple for backwards
compatibility), and accepts anything castable to Shape (including
enums, ranges, etc) anywhere a tuple was accepted previously.
In addition, `signed(n)` and `unsigned(n)` are added as aliases for
`Shape(n, signed=True)` and `Shape(n, signed=False)`, transforming
code such as `Signal((8, True))` to `Signal(signed(8))`.
These aliases are also included in prelude.
Preparation for #225 .

hdl.rec: unbreak hasattr(rec, ...).
...
hasattr() requires that AttributeError be raised. Change __getitem__
to raise AttributeError, too, since it is fundamentally just sugar
for getattr().

hdl.rec: allow providing fields during construction.
...
This allows creating records populated with e.g. signals with custom

hdl: make all public Value classes other than Record final.
...
In some cases, nMigen uses type() instead of isinstance() to dispatch
on types. Make sure all such uses of type() are robust; in addition,
make it clear that nMigen AST classes are not meant to be subclassed.
(Record is an exception.)
