Major features:
- Added Interval type, as well as PrimOps asInterval, clip, wrap, and sqz.
- Changed PrimOp names: bpset -> setp, bpshl -> incp, bpshr -> decp
- Refactored width/bound inferencer into a separate constraint solver
- Added transforms to infer, trim, and remove interval bounds
- Tests for said features

Fixes bug where arbitrary expressions, if called with .expr, return the
same expression.

Replace with more sensible comment to see LICENSE rather than including the
whole license in every file

Changed code from match statements in Mappers.scala to methods on the various
IR classes. This allows custom IR nodes to implement the mapper functions and
thus work (ie. not match error) when map is called on them.
This also should have a marginal performance increase because of use of virtual
function calls rather than match statements.

Indentation support for the ANTLR parser
- some clean-up of the parser code (TODO: file input could be improved, more clean-up)
- get rid of Translator and specify all syntactic rules in antlr4 grammer
- support for else-when shorthand in the grammar
- rename Begin to Block which makes more sense

trait AST -> abstract class FirrtlNode
Move all IR to new package ir
Add import of firrtl.ir._
