{,_}tools→{,_}utils
...
In context of nMigen, "tools" means "parts of toolchain", so it is
confusing to have a completely unrelated module also called "tools".

hdl.ast: deprecate shapes like (1, True) in favor of signed(1).
...
This is a great improvement in clarity.

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().
