The pass injects pipe registers immediately after the declaration of the
memory. This can be problematic if the clock for the associated memory
port is defined after the declaration of the memory. For any memory port
clocks that are driven by non-ports, we now inject a wire before the
pipe register declarations to be sure there are no
use-before-declaration issues.

* Fixes #2206

* Restore parsed MultiInfo structure in firrtl parser
* Change erroneous expected output in InfoSpec test
FileInfo compression sorts the outputted entries alphabetically, but
this test did not reflect that fact
* Fix typo in comment
* Add unit tests for file locator parsing
* Fix syntax issues and typos
* More redundant braces removed

* smt: include firrtl statement names in SMT and btor2 output
* smt: remove println
* smt: make tests run again and fix stale ones
Apparently `private` classes aren't found by th sbt test runner.

Add a new option to the FIRRTL compiler, "--start-from = <form>". If
used, this will cause the compiler to assume that the input FIRRTL
circuit is already in the specific form. It will then skip unnecessary
passes given this information.
E.g., if a user requests to run "firrtl -X verilog --start-from low"
then the compiler will only run transforms necessary to get from low
FIRRTL to Verilog. Transforms necessary for ingesting FIRRTL IR will be
run if needed (checks and type/kind/flow resolution).
To implement this, a CurrentFirrtlStateAnnotation is added. Advanced
users can use this directly to tell the FIRRTL compiler exactly what
transforms have already been run, including the ability to ignore checks
or type/kind/flow resolution if they so desire.

* Add Protocol Buffer emission export
This adds infrastructure and annotations that let a user emit a FIRRTL
circuit as a Protocol Buffer.
Fixes #1696.

* fixup! Add Protocol Buffer emission export

|
* make PresetRegAnnotation public
this annotation is useful outside the firrtl compiler:
- to implement a pass that creates registers which
need to be initialized at the beginning of simulation
(e.g., for formal verification)
- to support preset registers in treadle
* add PresetRegAnnotation test and deal with annotation correctly in RemoveReset pass

Add a compiler/emitter that can target minimal high form. This will
produce output that only has CHIRRTL constructs removed.

LowerTypes creates a lot of mappings for the RenameMap. The built-in
.distinct of renames becomes a performance program for designs with
deeply nested Aggregates. Because LowerTypes does not create duplicate
renames, it can safely eschew the safety of using .distinct via a
private internal API.

This function will safely wrap any unserializeable annotations in
UnserializeableAnnotations so that they can be safely serialized to JSON
for logging.

* Implement MFC-style source locator compression
* Fix formatting issues
* Fix emitting empty FileInfo if the firrtl doesn't have one
* Remove '.scala' requirement in FileInfo parsing regex
* Handle parsing of FileInfos with no line/col nums
* Split FileInfos only if they match
This should fix any issues with FileInfos that do not use the "file line:col"
format, and allow any valid firrtl using these info comments to compile.
* Add unit tests for locator compression
* Move InfoTests to InfoSpec class
* Fix existing unit tests with fileinfo comments
* Add unit tests to ignore the algorithm's own output
