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.

Upstream sifive/chisel-circt.

Or: now we're cooking with MLIR.

Use the published Ubuntu 20.04 binary of CIRCT to enable chisel-circt
tests in CI.

Move the git-subtree added sifive/chisel-circt repository from "circt/"
into "src/main/scala/circt/" and "src/test/scala/circtTests/".  Update
the chisel-circt README, which now lives in the src directory, to not
indicate that this is a published dependency anymore.

- Fix handling of EmitAllModulesAnnotation
- Fix stderr handling/erroring out if firtool errors during compile

Change GitHub CI to use a tagged, published Ubuntu binary of CIRCT
instead of relying on a nightly docker image.  This is both: (1) more
stable and (2) way faster.  This also removes a barrier to upstreaming
chisel-circt with chisel3.

We no longer meet on Tuesdays, only Mondays.

Release automation tries to bump chiseltest which causes issues due to
SBT trying to resolve all dependencies (even for projects that will not
be published, like integrationTests).

This is required in order to support peeks in
chiseltest.

Also remove all non-testing uses of chiselName.

Add support for the new, finer-grained aggregate preservation options
that were added to CIRCT/firtool.

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.
