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.

We have to set the SILFunction's 'weakLinked' flag in the defining
module too, so that it can be serialized. Otherwise when we
deserialize it we are not weak linking calls to the function.
This is like '@inlinable', except that the symbol does not have a public
entry point in the generated binary at all; it is deserialized and a copy
is always emitted into the client binary, with shared linkage.
Just like '@inlinable', if you apply this to an internal declaration it
becomes '@usableFromInline' automatically.
This uses the same mechanism as default arguments ever since Swift 4, so
it should work reasonably well, but there are rough edges with diagnostics
and such. Don't use this if you are not the standard library.
Fixes <rdar://problem/33767512>, <https://bugs.swift.org/browse/SR-5646>.
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.
This is a follow-up to https://github.com/apple/swift/pull/21783
which made `is{Setter}AccessibleFrom` respect `-disable-access-control`
flag. Now it's `getAdjustedFormalAccess` turn to do the same.
When printing its annotated decl, we would would assume the param's default
value is present if the default value kind was "Normal". The type checker
explicitly sets the default value to nullptr if it doesn't type check though, so
we were crashing for that case. Added the check.

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.
<rdar://problem/46420252>
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.
Previously, members of protocols that were not protocol requirements,
like accessors and typealiases, did not inherit @usableFromInline from
the parent protocol. Change this so they do.
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.
