Subject: Fixed bug with unary minus on FixedPoint and Interval (#2154)

In `Bits.scala`, `FixedPoint` and `Interval` did not defeine the `do_unary_-` methods (the `do_`) was missing
The recent PR #2124 combined with the above fact made DspTools break. This fix is necessary to get
that repo to build.---
