Argyrios Kyrtzidis 210f29f44b [libclang] Introduce clang_Cursor_getObjCSelectorIndex() function.
After getting a cursor with clang_getCursor for a particular source location,
allows querying the cursor in order to find out if the location points to a
selector identifier in an objc method or message expression, and which selector index it is.

Argyrios Kyrtzidis 191a6a86ad [libclang] Introduce clang_Cursor_getSpellingNameRange().
It retrieves a source range for a piece that forms the cursors spelling name.
Most of the times there is only one range for the complete spelling but for
objc methods and objc message expressions, there are multiple pieces for each
selector identifier.

Argyrios Kyrtzidis ab468b0381 Add info to ObjCPropertyRefExpr to indicate whether the dot syntax property
reference is going to message the setter, the getter, or both.

Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.

[AST/Sema]
-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.

[libclang]
-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.

The general idea has the seal of approval by John.

Daniel Dunbar 62ee6417ac [AST/Sema/libclang] Replace getSourceRange().getBegin() with getLocStart().
- getSourceRange().getBegin() is about as awesome a pattern as .copy().size().

I already killed the hot paths so this doesn't seem to impact performance on my
tests-of-the-day, but it is a much more sensible (and shorter) pattern.

Argyrios Kyrtzidis 4a280ff48f [PCH] Mark a PCH file with a flag to indicate if the serialized AST had
compiler errors or not.

-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.

[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.

The general idea is that we want libclang to stay functional even if a PCH had a compiler error.

Douglas Gregor 29c42f2a25 Implement a new type trait __is_trivially_constructible(T, Args...)
that provides the behavior of the C++11 library trait
std::is_trivially_constructible<T, Args...>, which can't be
implemented purely as a library.

Since __is_trivially_constructible can have zero or more arguments, I
needed to add Yet Another Type Trait Expression Class, this one
handling arbitrary arguments. The next step will be to migrate
UnaryTypeTrait and BinaryTypeTrait over to this new, more general
TypeTrait class.

Sebastian Redl 86fab844bb Make CXXNewExpr contain only a single initialier, and not hold the used constructor itself.
Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities.

This breaks the static analysis of new expressions. I've filed PR12014 to track this.

Argyrios Kyrtzidis 66f433a746 [libclang] API enhancements by Joe Groff!
- Exposes a CXType_Vector type kind for vector types.
- Adds generalized versions of the clang_getArrayElementType and clang_getArraySize functions, named clang_getElementType and clang_getNumElements, which work on array, vector, or complex types.
- Adds additional functions for querying function types. clang_isFunctionTypeVariadic returns true if a function type is variadic. clang_getFunctionCallingConv returns an enumeration value indicating the calling convention of the function type. clang_getNumArgTypes returns the number of static argument types, and clang_getArgType gets the type of an argument.
- Adds a clang_getTypedefDeclUnderlyingType function to get the underlying type from a TypedefDecl cursor.
- Adds a clang_getEnumDeclIntegerType function to get the integer type from an EnumDecl cursor.
- Adds clang_getEnumConstantDeclValue and clang_getEnumConstantDeclUnsignedValue functions to get the value of an EnumConstantDecl as a signed or unsigned long long, respectively.
- Exposes a CXCursor_AsmLabelAttr cursor kind for __asm__("label") attributes.
- Alters clang_getCursorSpelling to return the label value for AsmLabelAttr-kind cursors.
