The fake module names we create when indexing a Swift module divided into
'groups' (e.g. the stdlib) don't have to be valid Swift module names, but we
were manipulating them to be so. E.g. the stdlib "Lazy Views" group, became
"Lazy_Views". This name is displayed in some editors verbatim, and is also
used as input to some sourcekitd APIs (e.g. editor.open.interface) that only
work if the original group name is passed, rather than the processed one.
This patch stops mapping invalid module name characters like ' ' and '-' to '_'
so the original group name remains.

Several tests related to indexing system modules were taking a considerable
amount of time (100+ seconds in the worst case) indexing the standard library.
This adds a frontend option to skip it and updates those tests to pass it.
Two more pair of string conversion fixes. With this, I was able to build
swift master-next on Ubuntu 16.04 (didn't try anything downstream of
swift, and not sure if the tests pass).
* Reference is marked "explicit", which may be unexpected - the reason
is that the *call* is explicit, so we want to find it with e.g. rename,
or looking up callers, even though the identifier callAsFunction is
implicit. This matches the behaviour of initializers.
* The source location is the same as the base name (e.g. in `add3(5)`,
it would be at `add3`), which matches the behaviour of initializers.

When a “separately imported overlay” is added to a SourceFile, two things happen:
1. The direct import of the underlying module is removed from getImports*() by default. It is only visible if the caller passes ImportFilterKind:: ShadowedBySeparateOverlay. This means that non-module-scoped lookups will search _OverlayModule before searching its re-export UnderlyingModule, allowing it to shadow underlying declarations.
2. When you ask for lookupInModule() to look in the underlying module in that source file, it looks in the overlays instead. This means that UnderlyingModule.foo() can find declarations in _OverlayModule.
Replaces `ComponentIdentTypeRepr::getIdentifier()` and `getIdLoc()` with `getNameRef()` and `getNameLoc()`, which use `DeclName` and `DeclNameRef` respectively.
When Decl::getLoc() is called upon a serialized AST and the
serialized source location is available, we lazily open the
external buffer and return a valid SourceLoc instance pointing
into the buffer.
Like the last commit, SourceFile is used a lot by Parse and Sema, but
less so by the ClangImporter and (de)Serialization. Split it out to
cut down on recompilation times when something changes.
This commit does /not/ split the implementation of SourceFile out of
Module.cpp, which is where most of it lives. That might also be a
reasonable change, but the reason I was reluctant to is because a
number of SourceFile members correspond to the entry points in
ModuleDecl. Someone else can pick this up later if they decide it's a
good idea.
No functionality change.
Most of AST, Parse, and Sema deal with FileUnits regularly, but SIL
and IRGen certainly don't. Split FileUnit out into its own header to
cut down on recompilation times when something changes.
No functionality change.
Computing the interface type of a typealias used to push validation forward and recompute the interface type on the fly. This was fragile and inconsistent with the way interface types are computed in the rest of the decls. Separate these two notions, and plumb through explicit interface type computations with the same "computeType" idiom. This will better allow us to identify the places where we have to force an interface type computation.
Also remove access to the underlying type loc. It's now just a cache location the underlying type request will use. Push a type repr accessor to the places that need it, and push the underlying type accessor for everywhere else. Getting the structural type is still preferred for pre-validated computations.
This required the resetting of a number of places where we were - in many cases tacitly - asking the question "does the interface type exist". This enables the removal of validateDeclForNameLookup
Change Swift to work with the new FileManager API. It now returns and
ErrorOr<FileEntry*> instead of just the raw pointer.
(cherry picked from commit 257dbcd49d)
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.
