* 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.

* Don't invalidate ExtModule ports in an explicitInvalidate = true context
ExtModule ports were previously invalidated in the emitted FIRRTL, which is correct in a NonStrict / `Chisel._` compatibility context but not in newer chisel3 code where `explicitInvalidate = true`.

* 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
does not make sense to issue warnings about the current clock in this
context.

* Add OpaqueType support to Records (#2662)

#2612) (#2620)
* Refactor TruthTable.apply and add factory method for Espresso (#2612)
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.

* Define leading '_' as API for creating temporaries
Chisel and FIRRTL have long used signals with names beginning with an
underscore as an API to specify that the name does not really matter.
Tools like Verilator follow a similar convention and exclude signals
with underscore names from waveform dumps by default. With the
introduction of compiler-plugin prefixing in Chisel 3.4, the convention
remained but was hard for users to use unless the unnnamed signal
existed outside of any prefix domain. Notably, unnamed signals are most
useful when creating wires inside of utility methods which almost always
results in the signal ending up with a prefix.
With this commit, Chisel explicitly recognizes signals whos val names
start with an underscore and preserve that underscore regardless of any
prefixing. Chisel will also ignore such underscores when generating
prefixes based on the temporary signal, preventing accidental double
underscores in the names of signals that are prefixed by the temporary.
