Change Swift to work with the new FileManager API. It now returns and
ErrorOr<FileEntry*> instead of just the raw pointer.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances in the swift repo.
Since the return value of getAccessor() depends on mutable state, it
does not make sense in the request evaluator world. Let's begin by
removing some utility methods derived from getAccessor(), replacing
calls to them with calls to getAccessor().
Apart from mildly speeding up indexing, this also keeps the compiler
from running into issues with implementation-only imports that may not
be present while we're trying to index.

The backing property for 'foo' is now '_foo', and the projected value '$foo'.
This updates Indexing to report occurrences of foo within both $foo and
_foo occurrences (rather than just $foo - the old _foo).
FindRelatedIdents was similarlar updated, so it reports 'foo' ranges in both
_foo and $foo.
CursorInfo now reports the USR, documentation, and location of foo when invoked
occurrences of $foo or _foo, but now leaves the name, type, and annotated
declaration of _foo/$foo as is. Having the same USR ensures rename invoked on
any of them will still rename via foo. Reporting foo's documentation comment
instead is just to present something more useful to the user.
Make sure they handle the case when a property wrapper type's constructor is
called with the first argument coming from the var initializer, and the rest
from the custom attribute's argument.
This is the final piece to get rename and findRelatedIdents to include all foo
and $foo occurrences, for example, in the set of occurrences to be renamed or
shown, regardless of whether they were initiated on a foo or $foo.
Resolves rdar://problem/51695783.
This patch achieves this by updating indexing to reporting the position of
`foo` in occurrences of `$foo` as an occurrence of the `foo` symbol, so
that renames initiated on occurrences of the `foo` symbol will also result
in occurrences of the `$foo` symbol being updated correctly. This also means
find-references on foo will show places where $foo is used.
Making rename work in the other direction (invoking rename on $foo upating foo
occurrences too) is still todo.
This fixes custom attribute syntax highlighting on parameters and functions
(where function builders can be applied). They weren't being walked in
the function position previously and were walked out of source order in the
parameter position.
It also fixes rename of the property wrapper and function builder type
names that can appear in custom attributes, as well as rename of property
wrapper constructors, that can appear after the type names, e.g.
`@Wrapper(initialValue: 10)`. The index now also records these constructor
occurrences, along with implicit occurrences whenever a constructor is
called via default value assignment, e.g. `@Wrapper var foo = 10`, so that
finding calls/references to the constructor includes these locations.

This has been an unnecessary code path for a long time now and should be removed particularly because it triggers wasteful `stat` calls.

The determination of whether a property is memberwise-initialized is
somewhat confused for properties that have synthesized backing properties.
Some clients (Sema/Index) want to see the declared properties, while others
(SILGen) want to see the backing stored properties. Add a flag to
`VarDecl::isMemberwiseInitialized()` to capture this variation.
This utility was defined in Sema, used in Sema and Index, declared in
two headers, and semi- copy-pasted into SILGen. Pull it into
VarDecl::isMemberwiseInitialized() and use it consistently.
To represent the abstracted interface of an opaque type, we need a generic signature that refines
the outer context generic signature with an additional generic parameter representing the underlying
type and its exposed constraints. Opaque types also need to be keyed by their originating decl, so
that we can treat values of the same opaque type as the same. When we check a FuncDecl with an
opaque type specified as its return type, create an OpaqueTypeDecl and associate it with the
originating decl. (A representation for *types* derived from the opaque decl will come next.)
When building the implicit subscript expression, set the "implicit" bit
correctly and pass it through in the indexer so that we get implicit
refernces to the subscript. This would be useful for e.g. searching for
all uses of the dynamic subscript.
Fixes various places where we assume that only a VarDecl can be static so they operate on any AbstractStorageDecl instead. NFC until static subscripts are added.
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.

This is an attribute that gets put on an import in library FooKit to
keep it from being a requirement to import FooKit. It's not checked at
all, meaning that in this form it is up to the author of FooKit to
make sure nothing in its API or ABI depends on the implementation-only
dependency. There's also no debugging support here (debugging FooKit
/should/ import the implementation-only dependency if it's present).
The goal is to get to a point where it /can/ be checked, i.e. FooKit
developers are prevented from writing code that would rely on FooKit's
implementation-only dependency being present when compiling clients of
FooKit. But right now it's not.

...in preparation for me adding a third kind of import, making the
existing "All" kind a problem. NFC, except that I did rewrite the
ClangModuleUnit implementation of getImportedModules to be simpler!
We weren't renaming all occurrences of 'x' in the cases like the below:
case .first(let x), .second(let x):
print("foo \(x)")
fallthrough
case .third(let x):
print("bar \(x)")
We would previously only rename occurrences within the case statement the query
was made in (ignoring fallthroughs) and for cases with multiple patterns (as in
the first case above) we would only rename the occurrence in the first pattern.
This is a follow up to the discussion on #22740 to switch the host
libraries to use the `target_link_libraries` rather than the
`LINK_LIBRARIES` special handling. This allows the dependency to be
properly tracked by CMake and allows us to use the more modern syntax.
When conforming to a protocol, the index should have a "override"
relation for each witness, including type witnesses. This was
accidentally broken in 3bd80e5e31 when we stopped using the
type-checker to find all protocol conformances.

When debugging Objective-C or C++ code on Darwin, the debug info
collected by dsymutil in the .dSYM bundle is entirely
self-contained. It is possible to debug a program, set breakpoints and
print variables even without having the complete original source code
or a matching SDK available. With Swift, this is currently not the
case. Even though .dSYM bundles contain the binary .swiftmodule for
all Swift modules, any Clang modules that the Swift modules depend on,
still need to be imported from source to even get basic LLDB
functionality to work. If ClangImporter fails to import a Clang
module, effectively the entire Swift module depending on it gets
poisoned.
This patch is addressing this issue by introducing a ModuleLoader that
can ask queries about Clang Decls to LLDB, since LLDB knows how to
reconstruct Clang decls from DWARF and clang -gmodules producxes full
debug info for Clang modules that is embedded into the .dSYM budle.
This initial version does not contain any advanced functionality at
all, it merely produces an empty ModuleDecl. Intertestingly, even this
is a considerable improvement over the status quo. LLDB can now print
Swift-only variables in modules with failing Clang depenecies, and
becuase of fallback mechanisms that were implemented earlier, it can
even display the contents of pure Objective-C objects that are
imported into Swift. C structs obviously don't work yet.

This reverts commit 121f5b64be.
Sorry to revert this again. This commit makes some pretty big changes. After
messing with the merge-conflict created by this internally, I did not feel
comfortable landing this now. I talked with Saleem and he agreed with me that
this was the right thing to do.
The key thing here is that all of the underlying code is exactly the same. I
purposely did not debride anything. This is to ensure that I am not touching too
much and increasing the probability of weird errors from occurring. Thus the
exact same code should be executed... just the routing changed.
Module references get indexed as a 'module' symbol; they get USRs similar to how clang would assign a USR for a module reference.
