* Catch exceptions and convert to internal error.
We need to update the displayed message to incorporate a line number and text to be used for the issue.
* Cleanup exception handling/throwing.
Re-throw expected (or uncorrectable exceptions).
Provide Utils.getThrowable() to get the first (eldest) or last throwable in the chain.
Update tests to conform to FreeSpec protocol.
* Minor cleanup
Admit we've updated some deprecated ScalaTest methods.

indices should be read ports
|
|
* Spec features added: AnalogType and Attach
AnalogType(width: Width):
- Concrete syntax:
wire x: AnalogType<10>
- New groundtype, very restricted in use cases.
- Can only declare ports and wires with Analog type
- Analog types are never equivalent, thus if x and y have Analog
types: x <= y is never legal.
Attach(info: Info, source: Expression, exprs: Seq[Expression]):
- Concrete syntax:
attach x to (y, z)
- New statement
- Source can be any groundtyped expression (UInt, SInt, Analog, Clock)
- Exprs must have an Analog type reference an instance port
- Source and exprs must have identical widths
Included WDefInstanceConnector to enable emission of Verilog inout
Should be mostly feature complete.
Need to update spec if PR gets accepted.
* Fixed bug where invalidated ports aren't handled
* Bugfix for VerilogPrep
Intermediate wires for invalidated instance ports were not invalidated
* Bugfix: calling create_exp with name/tpe
Returns unknown gender, which was passing through
Caused temporary wire to not be declared
Because Verilog is dumb, undeclared wires are assumed to be 1bit signals
* Addressed donggyukim's style comments
* Reworked pass to only allow analog types in attach
Restrict source to be only wire or port kind
Much simpler implementation, almost identical functionality
Clearer semantics (i think?)
* Fixup bugs from pulling in new changes from master
* comments for type eqs and small style fixes
