ClangImporter::lookupTypeDecl allows a Clang type declaration to be
imported by Clang name instead of by Swift name. Now that we're using
Clang names in mangled names, that's exactly what we need to
reconstruct an AST type from a mangled name.
Also:
- Handle @compatibility_alias in ClangImporter::lookupTypeDecl
- Print errors when type reconstruction fails in swift-ide-test
- Add an extra test for RemoteAST
The original hope was we could make these heuristics really good, but
since that is not currently in sight (and may never be), we want to be
able to turn them off. For now, just plumb through an internal flag to
control the behaviour. A future change will customize the behaviour in
SourceKit.

- Outlaw duplicate input files, fix driver, fix tests, and add test.
- Reflect that no buffer is present without a (possibly pseudo) named file.
- Reflect fact that every input has a (possible pseudo) name.
- Break up CompilerInstance::setup.
Don't bail on dups.
This adds a -disable-objc-interop flag to allow objc-interop
to be disabled, and an -enable-objc-interop flag to
allow objc-interop to be enabled.
Objc interop will default to enabled on darwin, and disabled on
other platforms.
Encapsulate uses of the variables in FrontendInputs with intention-describing functions. Move some code that sets these variables into FrontendInputs and FrontendOptions classes.
Create new FrontendInputs class to encapsulate InputFilenames, InputBuffers and PrimaryInput, which were formerly in Frontend.
Includes one change in SwiftEditor.cpp to resolve a merge conflict.
This patch allows Parser to generate a refined token stream to satisfy tooling's need. For syntax coloring, token stream from lexer is insufficient because (1) we have contextual keywords like get and set; (2) we may allow keywords to be used as argument labels and names; and (3) we need to split tokens like "==<". In this patch, these refinements are directly fulfilled through parsing without additional heuristics. The refined token vector is optionally saved in SourceFile instance.
"Accessibility" has a different meaning for app developers, so we've
already deliberately excised it from our diagnostics in favor of terms
like "access control" and "access level". Do the same in the compiler
now that we aren't constantly pulling things into the release branch.
Rename AccessibilityAttr to AccessControlAttr and
SetterAccessibilityAttr to SetterAccessAttr, then track down the last
few uses of "accessibility" that don't have to do with
NSAccessibility. (I left the SourceKit XPC API alone because that's
supposed to be more stable.)

This commit changes the 'Accessibility' enum to be named 'AccessLevel'.
Typo correction can be particularly expensive, so introduce a
command-line flag to limit the number of typo corrections we will
perform per type-checker instance. Default this limit to 10.
Addresses rdar://problem/28469270 to some extent.
With the introduction of special decl names, `Identifier getName()` on
`ValueDecl` will be removed and pushed down to nominal declarations
whose name is guaranteed not to be special. Prepare for this by calling
to `DeclBaseName getBaseName()` instead where appropriate.
This changes `getBaseName()` on `DeclName` to return a `DeclBaseName`
instead of an `Identifier`. All places that will continue to be
expecting an `Identifier` are changed to call `getBaseIdentifier` which
will later assert that the `DeclName` is actually backed by an
identifier and not a special name.
For transitional purposes, a conversion operator from `DeclBaseName` to
`Identifier` has been added that will be removed again once migration
to DeclBaseName has been completed in other parts of the compiler.
Unify approach to printing declaration names
Printing a declaration's name using `<<` and `getBaseName()` is be
independent of the return type of `getBaseName()` which will change in
the future from `Identifier` to `DeclBaseName`

independent of the return type of `getBaseName()` which will change in
the future from `Identifier` to `DeclBaseName`
Replace `NameOfType foo = dyn_cast<NameOfType>(bar)` with DRY version `auto foo = dyn_cast<NameOfType>(bar)`.
The DRY auto version is by far the dominant form already used in the repo, so this PR merely brings the exceptional cases (redundant repetition form) in line with the dominant form (auto form).
See the [C++ Core Guidelines](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#es11-use-auto-to-avoid-redundant-repetition-of-type-names) for a general discussion on why to use `auto` to avoid redundant repetition of type names.
At the time this code was written, the logic to find a Decl from a
demangled name still lived in LLDB. Now that it's been sunk into
libIDE, we can test the actual behavior, though I've changed it to
find declarations rather than types.
This is kind of a pain, but it's better than the laundry list of
weird LLVM implementation details -help used to include. Someone
with more time than me can go back and actually put swift-ide-test's
options into proper categories.
(An alternate solution would be to use
llvm::cl::ResetCommandLineParser and /then/ initialize all the
options, but that would mean not making them available globally in
swift-ide-test.cpp.)
