This includes:
- bumping the SWIFT_SYMBOLGRAPH_FORMAT_MINOR version
- introduction of the "swift.extension" symbol and "extensionTo" relationship
- adding support for ExtensionDecl to the Symbol class
- adding a "typeKind" field to the symbol's extension mixin which indicates what kind
of symbol was extended
- intoduction of the -emit-extension-block-symbols flag, which enables the behavior
outlined below
- adaptions to SymbolGraphASTWalker that ensure a swift.extension symbol is emitted
for each extension to a type that does not exist in the local symbol graph
- adaptions to SymbolGraph and SymbolGraphASTWalker that ensure member and conformance
relationships are correctly associated with the swift.extension symbol instead of
the original type declaration's (extended nominal's) symbol where applicable
- adaptions to SymbolGraphASTWalker that ensure swift.extension symbols are connected
to their respective extended nominal's symbol using an extensionTo relationship
Testing:
- adds SymbolGraph tests that test behavior only relevant in
-emit-extension-block-symbols mode
- adapts some SymbolGraph tests to additionally test similar behavior for
extensions to external types in -emit-extension-block-symbols mode
- adapts some SymbolGraph tests to (additionally or exclusively) test the
behavior with -emit-extension-block-symbols mode enabled
Bugfixes:
- fixes a bug where some conformsTo relationships implicated by the conformances
declared on an extension to an external type were not emitted
(see test/SymbolGraph/Relationships/ConformsTo/Indirect.swift)
Further changes:
- documents the strategy for naming and associating children declared in extensions
to typealiases (see test/SymbolGraph/Relationships/MemberOf/Typealias.swift,
test/SymbolGraph/Symbols/Names.swift)
* only include the given symbol for qualified imports
rdar://96309088
* re-exporting one type should not allow unrelated types to sneak in
* ensure that children of re-exported types are also re-exported
* Revert "Revert "consider requirements of an underscored protocol to also be underscored""
* make SkipsPublicUnderscore more resilient to non-determinism
* move symbol graph samples to the bottom of the file
* add information about a doc comment's file and module
rdar://81190369
* refactor: group file URI collection/serialization together
* test for docComment.module to identify externally-inherited docs
When emitting a symbol graph file for a module that import modules via
`@_exported import`, emits those modules' symbols as well.

Rather than checking the underlying ObjectiveC decl, use the presence of
`OptionalAttr` to determine if a requirement is optional instead. This
is already added by the importer when necessary. An added benefit here
is that this also works for optional requirements defined in Swift (ie.
`@objc optional ...`).
