Don't use MuxLookup default for full mapping

This modifies MuxLookup to not use the 'default' mapping argument if a
"full" mapping is provided. A "full" mapping enumerates all possible
cases for a 'key' argument of a known size. This will check literal
values to ensure exhaustiveness holds.

Accomplished by changing the code gen for casting literals to
aggregates. Rather than connecting the literal to a wire that is then
bit selected from, just bit select from the literal which saves the
creation of an intermediate wire and matches FIRRTL's semantics for
legal async reset initial values.

Improve naming of anonymous/class-in-function Modules

Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

This changes the desired name of a Module to provide non-numeric
naming for anonymous Modules and Modules defined inside function
bodies.

Make ChiselStage targets not private

This enables users to use the nice run method of `ChiselStage` with their own set of phases.

Internal BoringUtils.bore Bug Fix

Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

This fixes a bug where internal boring using BoringUtils.bore would
fail because it was using instanceName which cannot be called before
the module closes. Previously, this meant that BoringUtils.bore would
work for boring instances (which are closed in a parent), but not for
boring signals in the current, unclosed module.

Plan to be released with 3.3.

Breaks experimental Range API.
Adds new Interval type and associated support.

This commit adds the following:

- Renamed Range to IntervalRange to avoid name collision with scala Range
- Changed RangeTransform macro to Return an IntervalRange
  - Improved error messages on missing comma or decimal
  - Added notational support for binary point
  - Some formatting cleanup also
- SIntFactory
  - Change to use IntervalRange API
- UIntFactory
  - UInt from range has custom width computation
    - It does not need to deal with lowerbound extending bit requirements
    - Code to handle special case of range"[0,0]" to have a width of 1
- IR.scala
  - Removed Bound and other constraint code that was duplicating firrtl stuff
  - Added new RangeType
  - Added IntervalRange class and object
- RangeSpec
  - modified just a bit to handle notational differences
    - previous range interpolator returned tuple now returns IntervalRange
- Add IntervalType to emitter
- Added IntervalSpec with many tests
- Added ScalaIntervalSimulatorSpec which tests golden model for Interval
- Added ScalaIntervalSimulator which is a golden model for Interval
  - This gold may not have been polished to a high sheen
- Add IntervalLit cases to Converter
- Add Interval PrimOps to IR
  - asInterval, wrap, squz, clip, setp, decp, incp
  - Add IntervalLit class to IR
- Add Interval to MonoConnect
- Add Interval Type to Bits (in experimental package)
  - add conversions to Interval from other types
- Add Interval clone stuff to Data
- Add Literal creation helpers to chisel3 package
  - these may move to experimental if I can figure that out
