* [WIP] Propagate source locators to Verilog if-else emission
* Add and fix tests for reg update info propagation
* Add limited source locator propagation in ConstProp
Support propagating source locators on connections or nodes where the
right-hand side is simply a reference. This case comes up a lot for
registers without a synchronous reset.
node _T_1 = x @[MyFile.scala 12:10]
node _T_2 = _T_1
z <= x
Previousy the source locator would be lost, now the result is:
z <= x @[MyFile.scala 12:10]
* Address review comments

This should speed up the common case
as the compiler never operates on the
unescaped string.
The new escape function also fixes a bug
where ']' was not escaped even though it
is the delimiting character for FileInfo.
In order to maintain backwards
compatibility for the ProtoBuf format,
this patch adds escape/unescape calls
when going from/to protobuf format.
For better performance we should consider
changing the protobuf format.

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
Plan to be released with 1.3

* Collects Infos found for symbols
* Merges multiple sources for symbol into MultiInfo
* Restores these Infos on connect statements.
* Add test showing preserved Infos
* Changed ++ methods on the Info sub-classes
* Ignore NoInfo being added
* Fixed way adding was implemented in MultiInfo
* Made InfoMap a class which defines the default value function

This transform replaces all wires with nodes in a legal, flow-forward
order
