There's no such node in the grammar. Pattern assignment statements
are simply expression statements whose expression is a
PatternAssignment (in the same way that a statement like `a = b;` is
an expression statement whose expression is `a = b`).

Overriding fields can change the type to remove nullability and
can also be final so they override the getters only.
For DDC that means there is an inherited setter that could still be nullable and a forwarding setter that should allow null even though
the type of the overriding field is non-nullable. With enhanced null
safety asserts enabled in weak mode there should be no failure when
setting the inherited field to null.

Functions returning non-nullable records of 2 fields can now return
them as separate values on 2 registers. This postpones and sometimes
eliminates creation of record instances. As other unboxing
optimizations of return values, this optimization is only
performed in AOT.
Pair of values for an unboxed record are represented using
kPairOfTagged representation, which can be now used for the input of
Return and for the output of StaticCall/InstanceCall
PolymorphicInstanceCall/DispatchTableCall instructions.
In order to combine separate values for Return, a new MakePair
instruction is added. Extracting separate values from the result of
a call is implemented using existing ExtractNthOutput instruction.

Asking for implementations of 'ToJsonable' from
package:analysis_server/lsp_protocol/protocol_special.dart takes
8+ seconds both on first request and on subsequent requests.
Turns out most of that is spent on getting line info data for each
result via `server.getLineInfo`.
This CL rewrites how the search is performed, getting all subtypes
directly via `searchAllSubtypes`, from which one can cheaply get the
line info.
On my machine, the call that always took 8+ seconds before now takes
<2 seconds (at least on subsequent runs).
Notice that the time also depends on how much is open by the editor and
that calls from my editor with many folders open still takes ~6 seconds.
This CL furthermore adds more performance measurements that's available
via the "Analysis Server Diagnostics" page "Timing" for
"textDocument/implementation" requests.

Fixes https://github.com/dart-lang/sdk/issues/50542
One primary principle is keeping the cost for _most code_
extremely low. Most code does not have an `examples/api`
directory. Most comments do not have `{@tool`.
Looking for directories on disk is expensive. Walking tokens
in comment text is cheap. So we can pay the price of walking all comments, prowling for `{@tool` text which we won't likely find,
and skip the work of looking for `examples/api` in _all_ parent
directories, until we find a comment with `{@tool`.
Don't check if `$parent/examples` exists before checking if `$parent/examples/api` exists. We don't care if `$parent/examples`
exists.
Don't create an `AanlyzerConverter` instance for _every element_
in a compilation unit while we are editing it. Instead, refactor
some of the `AnalyzerConverter` methods to be extension methods.

Previously, the VM used a linear array to cache previous instantiations
of a type arguments object. Now once the cache hits a certain number
of occupied entries, the VM changes to using a hash-based approach.
The InstantiateTypeArguments stubs have not yet been updated to
traverse the hash-based cache, so once the cache has grown too large,
all attempts at instantiations, even those that are in the cache, go to
the runtime. Thus, until the stubs are updated, this is only an
improvement if the cost of traversing the linear cache dominates the
cost of making a runtime call. Our benchmarks see a ~40% performance
regression for hash-based caches of size 100 but a ~400% performance
improvement for hash-based caches of size 1000. Thus, we currently
split the difference and set the maximum size of linear caches to 500.

Currently a File is created to make a lookup in a map with the key
being looked up being "file.path". I've seen examples where creating
this File - because of the call `FileSystemEntity._toUtf8Array(path)` in
`_File` (from the SDK) - adds 1+ seconds to a request.
Specifically, asking for implementations of 'ToJsonable' from
package:analysis_server/lsp_protocol/protocol_special.dart goes from
taking ~12.8 seconds to taking ~11.5 seconds (with enough workspace
folders open).
