Chris Fallin 0fb9c03e09 Version 0.4.0. (#84 )

This is identical to v0.3.3, but it turns out that the removal of the
register class from `SpillSlot` (#80) is an API change. I missed this
and published 0.3.3 but yanked it after it was causing build issues for
folks.

regalloc2: another register allocator

This is a register allocator that started life as, and is about 50% still, a port of IonMonkey's backtracking register allocator to Rust. In many regards, it has been generalized, optimized, and improved since the initial port, and now supports both SSA and non-SSA use-cases.

In addition, it contains substantial amounts of testing infrastructure (fuzzing harnesses and checkers) that does not exist in the original IonMonkey allocator.

See the design overview for (much!) more detail on how the allocator works.
