if given range can't be fully represented with specified precision, round to nearest relevant given open/closed info -- this is in creating intervals. Consider rethinking for anywhere IntervalRange is used

chisel doesn't pass open/closed-ness of ranges to firrtl with asInterval. Need to deal with ahead of time when bp + bounds are known. How about when they're not known?

revert old changes causing fp/interval lits to be incorrect (width wrong); corrected some interval related bounds (or made unknown) in IR

fix or remove some incorrect interval propagation in class Interval; also fixed some incorrect methods

.setBinaryPoint(that: Int)
.shiftLeftBinaryPoint(that: Int)
.shiftRightBinaryPoint(that: Int)
@azidar, please review

Added tests, which don't have any obvious errors

Added wrap(that: IntervalRange) API

Create generic wrap and clip methods that convert to UnknownBounds until
I can talk to Adam and figure out what I should do.
Add support for generating clip and wrap in Chirrtl

Tests forthcoming

Add a few tests for these.

This was because Range bases its width calculation on SInt bit
requirements

fix width check bug for negative FP and Interval lits -- SLit width check would fail after unsigned conversion. Width check wanted more bits than was necessary.
