#2935) (#2936)
* TruthTable improvements: structural equality and delete sort (#2935)
We had implemented equals, but not hashCode. This commit also changes
the implemental of equals to just use the underlying values instead of
wasting the compute calling .toString.
Delete TruthTable.sort, it is unused.
(cherry picked from commit b5d9c08b2d0994b94df2380425282206fe1f25bc)
* Restore and deprecate TruthTable.sort

* Promote ChiselEnum user APIs from experimental (#2929)
They are commonly used and if we were ever to change them, we will need
to go through a deprecation process anyway.
Note that the EnumAnnotations remain in chisel3.experimental because,
like all Chisel annotation support, they are slated to be deprecated and
removed.

#2907) (#2928)
* Check for Vec subaccess in NamedComponent and throw a nicer error. (#2907)
This would previously end up throwing an exception later, when trying
to create a component name and realizing that it was invalid. Instead,
this detects Vec subaccesses early, and gives a more precise error and
suggestion.

* Fix BitSet decoder API when errorBit=False

`Unit` which will be `()` in interpolated string.

* Make PriorityMux stack safe (#2854)
It used to be implemented with recursion, now it's implemented with a
stack safe reverse and foldLeft.
Also there were no tests for PriorityMux so I added one which helps
prove the change is functionally correct.

* Implement compressed Namespace (#2856)
The namespace disambiguates requests for the same name with _<idx>.
Rather than storing every disambiguated name in the underlying HashMap,
it now only stores the base along with the "next available" index. This
makes the logic for checking if a name is already contained in the
namespace slightly more sophisticated because users can name things in a
way that will collide with disambiguated names from a common substring.
For example, in naming the sequence "foo", "foo", "foo_1", the 2nd "foo"
takes the name "foo_1" so the following "foo_1" gets disambiguated to
"foo_1_1". But since we compressed that original "foo_1" into the same
HashMap entry as just "foo", we have to do a form of "prefix checking"
whenever naming something that ends in "_<idx>".
In practice, the saved memory allocations more than make up for the more
complicated logic to disambiguate names because the common case is still
fast.

* Switch to using experimental trait for OpaqueTypes (#2783)
This makes it more clear that the feature is experimental. Users may
still override the opaqueType method for more dynamic control over when
instances of a given Record are OpaqueTypes or not, but they are
discouraged from doing so.

#2829) (#2831)
* Add Aggregate.elementsIterator and micro-optimize
elementsIterator provides a more efficient API for iterating on the
elements of Aggregates. It is especially useful for Records where
getElements returns a Seq and thus eagerly constructs a new
datastructure which may then just be iterated on anyway.
This new elementsIterator API is then used throughout the codebase where
it makes sense.
Also change Vec.getElements to just return the underlying self instead
of constructing a new Seq.

* Move Aggregate.bind inline into Record.bind
Vec overrides bind and does not call the version in Aggregate so the
version in Aggregate is misleading in that its only ever used by
Records. Now there is no version in Aggregate and the actual
functionality and use is more clear.

* Add PartialDataView.supertype (#2826)
This factory method makes it easy to create PartialDataViews from a
Bundle type to its supertype. Because of the typing relationship, there
is no need to provide a mapping between fields. The only thing necessary
is to provide a function for constructing an instance of the supertype
from an instance of the subtype.

* Add opt-in AutoCloneType for Records (#2781)
There is a new trait, chisel3.experimental.AutoCloneType that is mixed
in to Bundle and can optionally be mixed in to user-defined Records. The
compiler plugin prints a deprecation warning on any user-defined
implementation of cloneType, telling the user to mix in AutoCloneType
before upgrading to 3.6.

* Remove incorrect clock warning on Mem.read (#2721)
Mem.read is combinational and thus unaffected by the clock, and so it

* Add OpaqueType support to Records (#2662)
