  1. Split Int into Int and MinInt 

    `MinInt` contains the basic methods that are only needed by integers
involved in widening operations, i.e. big integers. `Int` retains all
other operations and convenience methods.

  3. Refactor float test macros to have a fallback 

    Change float test macros to fall back to testing against `rustc_apfloat`
when system implementations are not available, rather than just skipping
tests.

This allows for easier debugging where operations may not be supported.
