We need to ensure that contextual names stay contextual (ie. sensitive
to the module context which is important for naming ports).

* Add OpaqueType support to Records (#2662)

OpaqueTypes are essentially type aliases that hide the underlying type.
They are implemented in Chisel as Records of a single, unnamed element
where the wrapping Record does not exist in the emitted FIRRTL.

* Fix test compilation

* Fix OpaqueType tests in RecordSpec

error) in 3.5.

* Ignore lack of plugin 3.5.3 artifact for Scala 2.12.16

Since 2.12.16 did not exist when 3.5.3 was published, there is no
artifact for the plugin so we must ignore it until 3.5.4 is released.

* Refactor TruthTable.apply and add factory method for Espresso (#2612)

Improves performance of creating TruthTables by processing entire BitPats
rather than individual bits. New TruthTable factory method enables
constructing TruthTables with semantics of OR-ing output BitPats together
rather than erroring when multiple terms have the same input BitPat.
This alternative factory method matches semantics for the output format
of Espresso.
