79ef13592e 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.

ad0bc66402 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.

dbc9b7f46e Reworked the error messages for more heplfulness.
Renamed the cast_possible_overflow lint to cast_possible_truncation,
and updated the error message, readme and crate root accordingly.
Added some more information to the message for the cast_precision_loss
lint.
Updated the test case to reflect changes.

993239d33a Initial implementation of lossy cast lints.

cab9905705 better help text for "match -> if let" lint
Implements the suggestion from #87.

Changes span_help_and_lint(), which is only used for this lint,
to use fileline_help() instead of span_help() to avoid printing
the span twice.

Also adds complete suggested new code. I had to distinguish
between blocks, which need no additionals braces, and other exprs.
