Completed the implementation of *size handling.
...
Added some more cases to the test, and implemented a new lint,
cast_possible_wrap, triggered when casting from an unsigned type to a
signed type of the same size.

all: put often used DefPaths into utils as consts
...
Also remove the "use xxx;" blocks to ensure import paths don't change.
They don't work anyway since stuff may still be re-exported at the old
location, while we need the "canonical" location for the type checks.
Plus, the test suite catches all these cases.

Added support for isize/usize in the CastPass lint pass.
...
Extracted the match that determines an integer types's size in a
utility function and implemented support for usize/isize.
Added a needed feature to the crate root.
Added some tests to cover those cases, and a test I previously forgot.
Silenced two errors signaled by dogfood.sh in unicode.rs.

Added some more information to the message for the cast_precision_loss
lint.
Updated the test case to reflect changes.
