From 6e03f63d525aac0bdf4a59b6fe66a0b4d5a3a25a Mon Sep 17 00:00:00 2001

Subject: Use ChiselStage in Tests

This migrates the tests to Chisel 3.4/FIRRTL 1.4. This primarily
involves removing usages of deprecated methods including:

- Remove usages of Driver
- Use ChiselStage methods instead of BackendCompilationUtilities
  methods
- Use Dependency API for custom transforms
- Use extractCause to unpack StackError
