`ValueDecl` is final.

26de7c1bf9 [index] Fix infinite loop while looking at superclasses
While checking for superclasses in isUnitTest, we need to handle
circular inheritance. For good measure, add tests for protocols as well.

The new API is designed to behave the same as walkInheritedProtocols
except that is walks over superclasses.

b50d878f5d [parse/sema] Give all case bodies their own var decls without using those var decls for anything.
This is a step in the direction of fixing the fallthrough bug. Specifically, in
this commit I give case stmts a set of var decls for the bodies of the case
statement. I have not wired them up to anything except the var decl
list/typechecking.

b1a7b488fd [sema] Wire up VarDecl parent pointers for case stmt related Var Decls
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. 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).

In a subsequent commit I am going to add case body var decls. The only change as
a result of that is that I will insert them into the VarDecl double linked list
after the last case var decl of each case stmt.

500f34c0ef [ast] Allow for VarDecls to have a Parent back pointer that points at a different var decl.
I did not wire anything up to it.

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.

1719f0cdf1 Serialization: Also serialize the filename for internal storage decls with private accessors
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.

d19d2f2490 [AST] Lazily compute ProtocolDecl::getKnownProtocolKind()
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.

bfcf24ee4e AST: Rework @objcMembers inheritance to not depend on validation order
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.

544e0a02d5 AST: Don't link together GenericParamLists of nested generic types
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.

ff63eaea6f Remove \brief commands from doxygen comments.
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.
