whitequark 11914a1e67 hdl.ast: improve interaction of ValueCastable with custom __getattr__. 
Avoid calling `__getattr__("_ValueCastable__lowered_to")` when
a ValueCastable has custom `__getattr__` implementation; this avoids
the need for downstream code to be aware of this implementataion
detail.

whitequark 818c8bc464 hdl.ast: normalize case values to two's complement, not signed binary. 
This was an especially insidious bug because the minus character is
valid in case values but has a completely different meaning (wildcard
rather than sign).

Fixes #559.

whitequark 67b957d4f4 tests: move out of the main package. 
Compared to tests in the repository root, tests in the package have
many downsides:
  * Unless explicitly excluded in find_packages(), tests and their
    support code effectively become a part of public API.
    This, unfortunately, happened with FHDLTestCase, which was never
    intended for downstream use.
  * Even if explicitly excluded from the setuptools package, using
    an editable install, or setting PYTHONPATH still allows accessing
    the tests.
  * Having a sub-package that is present in the source tree but not
    exported (or, worse, exported only sometimes) is confusing.
  * The name `nmigen.test` cannot be used for anything else, such as
    testing utilities that *are* intended for downstream use.
