* Switch from `@silent` to `@nowarn`.
This annotation is native to Scala 2.12.13+ and 2.13.2+. It replaces
most usages of `@silent`.
I had to get creative about a couple of use cases that didn't work.
Specifically:
1. Suppressing deprecation warnings works, but Scala 2.12 erroneously
complains that the `@nowarn` is unnecessary. I had to suppress
this warning too with `-Ywarn-unused:-nowarn`.
2. I can't seem to suppress the warning, "The outer reference in this
type test cannot be checked at run time." Instead, I have
refactored the code to remove the warning.
We still need to use the silencer plugin to suppress some warnings about
unused imports (because of compatibility between Scala 2.12 and 2.13),
but this means we no longer need the library, and therefore it is not a
transitive dependency that downstream consumers need to worry about.

* Add some comments around `@nowarn` support.
* language-support/scala: Fix a warning suppression.
* Revert to the default warnings.
Compatibility was complaining.
* Cache contract fetches in speedy
This PR adds a cache to speedy to cache contract fetches and
information only derived from the contract argument, namely,
signatories, observers and keys.
The cache is engine-internal so on the first fetch of a global
contract in a transaction, we recompute that information.
This does not change observable semantics:
Ledgers must be consistent within a transaction so caching is safe. We
still recompute signatories, observers & keys the first time so if
they fail, we still blow u.
We also never compute more than before. While `SBUFetch` itself did
not compute that information, it was immediately folowed by either
`SBUBeginExercise` or `SBUInsertFetchNode` which compute that
information.
We also keep the optimization that we do not have to compute key and
maintainers on by-key operations
On the collect authority benchmark, this is around a ~1.48x
improvement which is pretty decent.

This PR adds a hook in the compiler and the engine to allow easy prototyping of new features.
In particular by using this hook, one can add a new feature in 1.dev with modifying:
compiler
type checkers (both Haskell and Scala)
archive Protobuf
archive decoder
In addition of development speed, this also adds a bit of confidence, as the peaces enumerated above are not touched when adding the feature: The feature can be added by modifying only 1.dev Daml standard library and Speedy.
aa7991f8 shows a use case of this hook.

* Remove redundant list of LF versions
After #8472, I realized that there must be a list used for daml-stdlib
and daml-prim already and it turns out there is. I’ve removed that one
in favor of the one added in #8472 since I like having all in one
place and the one from #8472 is created by filtering an existing list
instead of creating a completely separate list like we do here.

This PR updates scalafmt and enables trailingCommas =
multiple. Unfortunately, scalafmt broke the version field which means
we cannot fully preserve the rest of the config. I’ve made some
attempts to stay reasonably close to the original config but couldn’t
find an exact equivalent in a lot of cases. I don’t feel strongly
about any of the settings so happy to change them to something else.
As announced, this will be merged on Saturday to avoid too many conflicts.

We use the constants defined in LanguageVersion/TransactionVersions instead
repeating the somewhat magic constants "6", "7", "8", "10" and "dev" in multiple places?
CHANGELOG_BEGIN
CHANGELOG_END
We drop the distinction (at the type level) of Dev and Stable language
version. The two main reason that motivate this choice:
* we never really used this distinction.
* we want to add the concept of "preview" version (which is neither Dev nor Stable)
CHANGELOG_BEGIN
CHANGELOG_END
This is necessary to at least attempt an upgrade to 2.13 and
generally, I want to keep our rulesets up2date. rules-scala forces the
version of scalatest so we have to bump that at the same time.
This requires changes to basically all Scala test suites since the
import structure has changed and a bunch of things (primarily
scalacheck support) got split out.
Apologies for the giant PR, I don’t see a way to keep it smaller.

* DAML-LF: Add interning for type to DAML-LF 1.dev
We add two new features to DAML-LF 1.dev:
* a per package list (or table) of `Type` messages, and
* a new case in the `Type` message which is an index into this table.
In combination, these two features can be used to allow DAML-LF
encoders to perform hash-consing of `Type` messages. We also change the
Haskell implementation of our DAML-LF encoder to do exactly that when
targetting DAML-LF 1.dev.
Doing this has a few benefits:
1. The DALFs produced by `damlc` get smaller: I've seen a case where
the size dropped from 69MB to 45MB.
2. DAML-LF decoders need to decode less data.
3. Decoded packages use less memory because identical structures are
now shared. This is particularly helpful in situations where we need
to keep the interface (or signature) of a package in memory for a
long time.
This PR mostly takes care of the Haskell implementation. However, we
need to make the Scala implementation of the decoder aware of the new
features as well since we have tests that load DAML-LF 1.dev into the
engine. A decoder and _targeted_ tests on the Scala side will follow
in a separate PR.

This is pretty much a verbatim copy of
https://github.com/digital-asset/daml/pull/7740, but for updates of
structural records instead of projections.
This has no immediate performance impacts since the DAML compiler does
_currently_ not produce any structural record updates. Having both,
projections and updates, have the same runtime characteristics seems to
be a desirable property nevertheless, simply to avoid nasty surprises
should we ever start to use these updates.
Since the compiler does not produce any structural record updates, I
have no way to benchmark this. However, since the code is changed here
in the same way it was changed in the PR mentioned above, I expect the
same saving, which were roughly 80 ns per operation, where the previous
cost of an operation was _at most_ 210 ns.
CHANGELOG_BEGIN
CHANGELOG_END
* Speed up projections of structural records
Currently, for every projection of a structural record, we first do a
linear search through the field names to find the index of the field
value in the record value. Then we use this index to get the actual
value. However, since we started sorting the fields in alphabetic order
both in types and in values, this lookup will always yield the same
result for a fixed record type and a fixed field name, regardless of the
value of the record.
This PR changes the AST node for structural record projection to
contain the index of the field within the record as well. This
information is not contained in the DAML-LF archive itself and must
hence be filled in by the DAML-LF type checker.
The only context in which we use structural record prejections are
typeclass method invocations, which do a little bit more than just the
projection. Unfortunately, typeclass method invocations are the small
unit of work I can benchmark using the setup I have. In the end, they
are also the feature our users really care about.
My benchmarks show that the time a single typeclass method invocation
takes has dropped from ca. 210ns to ca. 130ns. That's a speedup of
ca. 1.6x.
CHANGELOG_BEGIN
[DAML Interpreter] Typeclass method invocation is now 1.6x faster.
