Quickfix for LoadMemoryTransform that gets this to work with Instance
Annotations. The new Instance Annotations caused a corner case where a
LoadMemoryAnnotation would be duplicated (via update/renaming) and the
resulting annotation would differ from the original in only their
originalMemoryNameOpt field. This corrects that by having the
ChiselLoadMemoryAnnotation also emit the originalMemoryNameOpt field where
it did not previously.
First part of a fix for freechipsproject/firrtl#922.

* Ability to load memories at simulation startup
* first pass
* create annotation
* create skeleton Transform
* Work in progress
Building out transform and pass now
* Support for LoadMemory annotation
* Creates chisel and firrtl LoadMemory annotations
* LoadMemoryTransform converts annotation into BlackBox InLine
* Simple test that verilog bound modules get created.
* Support for LoadMemory annotation
* Supports Bundled/multi-field memories
* more tests
* support for `$readmemh` and `$readmemb`
* warns if suffix used in file specification.
* Support for LoadMemory annotation
* Use standard chisel annotation idiom
* Support for LoadMemory annotation
* Fixes for @seldridge nits and super-nits
* Support for LoadMemory annotation
- transform now only runs if emitter is an instance of VerilogEmitter
- suffixes on memory text files are now respected
- if suffix exists and memory is aggregate, aggregate sub-fields will now be inserted before suffix
- every bind module created gets a unique number
- this is required when multiple loaded memories appear in a module
- this should be generalized for other uses of binding modules
* Support for LoadMemory annotation
- remove un-needed suffix test
* Support for LoadMemory annotation
- remove instance walk, now just processes each module
* Support for LoadMemory annotation
- Move LoadMemoryTransformation into Firrtl for treadle to access it.
* Support for LoadMemory annotation
- One more bug in suffix handling has been eliminated
* Support for LoadMemory annotation
- remove unused findModule per jackkoenig
- fixed complex test, bad filename edge case
* Support for LoadMemory annotation
- changed to not use intellij style column alignment for : declarations
* Load memory from file
Fixes based on @jkoenig review
- remove unused BindPrefixFactory
- Moved code from CreateBindableMemoryLoaders into to LoadMemoryTransfrom
- Made map to find relevant memory annotations faster
- Made map to find modules referenced by annotations faster
- Made things private that should be private
- DefAnnotatedMemorys are no longer referenced, shouldn't be found here.
- println of error changed to failed
* Loading memories from files
- Many changes based on review
- move stuff into experimental
- clean up annotation manipulation
- manage tests better
- use more standard practices for transform
* Loading memories from files
- More review changes
- Move doc from annotation to the object apply method that generates the annotation
- Make scalastyle directives more specific
- Use more efficient collect to generate name to module map
- Made lines obey style length limit
- a couple of cleanups of imports in tests
- removed some commented out code
- optimized checking for lines using .exists
- use _ for unused variable in match

This adds a new trait, FlattenInstance, to chisel3.util.experimental. When
mixed into a module or a specific instance this trait will "flatten",
i.e., "inline that module and all of its submodules".
This includes testing (additions to InlineSpec) and ScalaDoc
documentation.

This adds an annotator that provides a linkage to the FIRRTL
WiringTransform. This enables synthesizable cross module references
between one source and multiple sinks without changing IO (the
WiringTransform bores through the hierarchy).
Per WiringTransform, this will connect sources to their closest
sinks (as determined by BFS) or fail if ownership is indeterminate.
Make TesterDriver.execute work like Driver.execute:
- annotations are included when running FIRRTL
- custom transforms are run automatically
Also, add a bore method to BoringUtils that allows you to do one source to
multi-sink mapping in a single call. This adds a test that this is doing
the same thing as the equivalent call via disjoint addSink/addSource.
