I did not wire anything up to it.
This is in preparation for fixing issues around SILGenPattern fallthrough
emission and bad rename/edit all in scope of case stmt var decls. Specifically,
I am going to ensure that we can get from any VarDecl in the following to any
other VarDecl:
switch x {
case .a(let v1, let v2), .b(let v1, let v2):
...
fallthrough
case .c(let v1, let v2), .d(let v1, let v2):
...
}
This will be done by:
1. Pointing the var decls in .d at the corresponding var decls in .c.
2. Pointing the var decls in .c at the corresponding var decls in .b.
3. Pointing the var decls in .b at the corresponding var decls in .a.
4. Pointing the var decls in .a at the case stmt. Recognizing that we are asking
for the next VarDecl, but have a case stmt, we check if we have a fallthrough
case stmt (which I am going to add in a subsequent commit). If so, follow down
the fallthrough case stmts until you find a fallthrough case stmt that doesn't
fallthrough itself and then return the corresponding var decl in the last case
label item in that var decl (in the above .d).
I also put in some asserts to make sure that we never try to vend a parent value
that is a nullptr.

The observer in a dynamic replacement of variables with a observer will
provide the dynamic replacement for the original.
var original : Int = 0 {
didSet {
print("original")
}
}
@_dynamicReplacement(for: original)
var replacement : Int = 0 {
didSet {
print("replacement")
}
}

If a value decl is internal hasTestableOrPrivateImport will succeed (or
fail) without looking at the filename. However this breaks when we query
an internal storage decl with private formal access for a private
setter: the query would fail because no filename was serialized for the
decl (we only serialize filenames for private decls). So in the special
case of a internal storage with private accessor also serialize the
filename.

Rather than eagerly doing a bunch of name lookups to establish the known
protocol kind, lazily match the ProtocolDecl to the list of known
protocols as-needed. This eliminates a bunch of up-front unqualified
name lookups when spinning up a type checker.
Sema would directly check for the presence of the @objcMembers attribute,
and inherit it from the immediate superclass in validateDecl().
We don't want validateDecl() to have side effects like this and this was
already a problem, because it would not inherit the attribute transitively
in some cases.
Instead, add a ClassDecl::hasObjCMembers() method that walks over all
ancestors and caches the result.

GenericParamList::OuterParameters would mirror the nesting structure
of generic DeclContexts. This resulted in redundant code and caused
unnecessary complications for extensions and protocols, whose
GenericParamLists are constructed after parse time.
Instead, lets only use OuterParameters to link together the multiple
parameter lists of a single extension, or parameter lists in SIL
functions.
For now Sema still calls it manually, but soon we could make
getGenericParams() lazy, calling this automatically, since
there's really no reason to create the generic parameters
upfront when binding the extension.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

We want removing a property override to be a resilient change, so
keypaths should not reference them, preferring to reference the
base declaration instead.
Instead of passing in a DeclContext, which we don't have when emitting a keypath
accessor, pass in a ModuleDecl and ResilienceExpansion.
Keypaths now work well enough in inlinable contexts that we can check in an
end-to-end resilience test.
`typeCheckParameterDefault` is used to type-check default value
expression associated with a given parameter. It makes it possible
to look-through `@autoclosure` function to use its result as
contextual type, and later build implicit autoclosure expression
if needed.
Not NFC because it also fixes an evaluation order bug (and reorders
some less-important stuff): the key-path expression needs to be
evaluated immediately during formal evaluation and cannot be delayed
until start-of-access.
A module compiled with `-enable-private-imports` allows other modules to
import private declarations if the importing source file uses an
``@_private(from: "SourceFile.swift") import statement.

Add parsing, type checking, serialization, and deserialization support
for specifying multiple types as "designated" for operator lookup for
a given operator declaration.
The constraint solver still considers only the first type when
deciding the order to attempt the elements of a disjunction, so this
doesn't really change behavior yet.
Update the representation to allow for multiple types to be specified
for a single operator.
No parsing, serialization, or deserialization support yet, so NFC.
