Rather than using `ModuleDecl::isSystemModule()` to determine whether a
module is not a user module, instead check whether the module was
defined adjacent to the compiler or if it's part of the SDK.
If no SDK path was given, then `isSystemModule` is still used as a
fallback.

Previously enum AccessLimitKind was
added to distinguish access scopes b/t package and public while keeping
DeclContext null but it proved to be too limiting. This PR creates package specific entries for DeclContext and
ASTHierarchy. It create a new class PackageUnit that can be set as the parent DeclContext of ModuleDecl. This PR
contains addition of such entries but not the use of them; the actual use of them will be in the upcoming PRs.

Various requests expect to be walking over the current source file.
While we could add checks to all these to skip decls outside of the
current buffer, it's a little nicer to handle this during the walk
instead.
Allow ignoring nodes that are from macro expansions and add that flag to
the various walks that expect it.
Also add a new `getOriginalAttrs` that filters out attributes in
generated source.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

Replace the use of bool and pointer returns for
`walkToXXXPre`/`walkToXXXPost`, and instead use
explicit actions such as `Action::Continue(E)`,
`Action::SkipChildren(E)`, and `Action::Stop()`.
There are also conditional variants, e.g
`Action::SkipChildrenIf`, `Action::VisitChildrenIf`,
and `Action::StopIf`.
There is still more work that can be done here, in
particular:
- SourceEntityWalker still needs to be migrated.
- Some uses of `return false` in pre-visitation
methods can likely now be replaced by
`Action::Stop`.
- We still use bool and pointer returns internally
within the ASTWalker traversal, which could likely
be improved.
But I'm leaving those as future work for now as
this patch is already large enough.
If a 'nil' literal occurs in a swift-case statment, it gets replaced by a reference to 'Optional.none' in the AST. We want to continue highlighting 'nil' as a keyword and not as an enum element.

This allows makes the distinction between cachable and non-cachable properties cleaner and allows us to more easily compute contextual information (like type relations) for cached items later.
MSVC doens't pack diffrent underlying int types into a bitfield. e.g.
struct S {
int a: 1;
char b: 1;
int c: 1;
};
These fields are considered three sparate bitfields.
A keypath using dynamic member lookup results in various `KeyPathExpr`
that have components with no location. Ignore these and any other
references that have a missing location.

Othwerise we were performing the syntactic parsing on a background queue that had a reduced stack size which could result in stack overflows.

* Fix unnecessary one-time recompile of stdlib with -enable-ossa-flag
This includes a bit in the module format to represent if the module was
compiled with -enable-ossa-modules flag. When compiling a client module
with -enable-ossa-modules flag, all dependent modules are checked for this bit,
if not on, recompilation is triggered with -enable-ossa-modules.
* Updated tests
The key changes here are
- To keep track of cancellation tokens for all `ScheduledConsumer`s in `SwiftASTManager`
- Generate unique request handles for all incoming requests (`create_request_handle `), use these request handles as cancellation tokens and return them from the `sourcekitd_send_request` methods
- Implement cancellation with `sourcekitd_cancel_request` as the entry point and `SwiftASTManager::cancelASTConsumer` as the termination point
Everything else is just plumbing the cancellation token through the various abstraction layers.

The index build skips *all* function bodies, including inlinable. The
`OSLogOptimization` pass expects SIL for inlinable bodies and thus
outputs a spurious diagnostic for live issues when the
`OSLogInterpolation` extension is in a separate module to the log
statement.
Ignore this for now, but we may need to re-evaluate if this becomes a
more widespread problem.

During a cursor info request, the resolved offset was mapped to line and
column using the buffer inside `SwiftDocumentSyntaxInfo`.
However, prior to 54683ca607,
`editorReplaceText` was not updating the syntax info. This meant that
snapshots would be more up to date than the buffer in the syntax info,
allowing for the possibility of an invalid offset.
While 54683ca607 would also fix this,
snapshots actually have a `getLineAndColumn` anyway. Use that instead of
grabbing the buffer from syntax info.
Resolves rdar://78161348.
Previously, if the client requests no information from "edit" request,
the syntax info wasn't updated. But "expand placeholder" request
requires the up-to-date syntax info.

We were only keeping track of `RawSyntax` node IDs to incrementally transfer a syntax tree via JSON. However, AFAICT the incremental JSON transfer option has been superceeded by `SyntaxParseActions`, which are more efficient.
So, let’s clean up and remove the `RawSyntax` node ID and JSON incremental transfer option.
In places that still need a notion of `RawSyntax` identity (like determining the reused syntax regions), use the `RawSyntax`’s pointer instead of the manually created ID.
In `incr_transfer_round_trip.py` always use the code path that uses the `SyntaxParseActions` and remove the transitional code that was still using the incremental JSON transfer but was never called.
In order to make range-shifting for semantic highlighting testable,
disable returning semantic information during an "open" request. This
has no real value anyway, since it only happens very rarely, and it
makes testing range shifting impossible to do deterministically.

When performing an insertion (replacement length = 0) inside an existing
annotation, we were forming a closed range instead of a half-open range,
causing us to shift the effected token instead of throwing it out. There
were also no tests for this functionality, so add a bunch of annotations
tests.
One area thing that is not tested is what if there have been multiple
edits since the tokens were created. This is difficult to engineer,
because right now making an edit immediately removes the semantic tokens
and returns them. It could happen if the AST build takes longer than the
edits, but there is no way to guarantee that in the current API.

Return type in the closure signature is often redundant when expanding
placeholders, because the type of the clossures are usually inferred
from the context (i.e. calling function), users don't need to write the
return type explicitly.
They are not only redundant, but also sometimes harmful when the return
type is a generic parameter or its requirement. Actually, there is no
correct spelling in such cases.
So omit the return type and the parentheses around the parameter clause.

Do not remove semantic annotations, so that if a client sends multiple
magic replacetext 0, 0, "" requests they will all return the same
result. This makes sourcekitd more robust around providing semantic
highlighting if the editor may make multiple queries for document
update.

Single-expression closures have always been traversed differently
from multi-statement closures. The former were traversed as if the
expression was their only child, skipping the BraceStmt and implicit
return, while the later was traversed as a normal BraceStmt.
Unify on the latter treatment, so that traversal
There are a few places where we unintentionally relied on this
expression-as-child behavior. Clean those up to work with arbitrary
closures, which is an overall simplification in the logic.
Currently when parsing a SourceFile, the parser
gets handed pointers so that it can write the
interface hash and collected tokens directly into
the file. It can also call `setSyntaxRoot` at
the end of parsing to set the syntax tree.
In preparation for the removal of
`performParseOnly`, this commit formalizes these
values as outputs of `ParseSourceFileRequest`,
ensuring that the file gets parsed when the
interface hash, collected tokens, or syntax tree
is queried.
