Formatter: Support @public/@protected/@package/@private.

@package is an Objective-C 2 feature, so turn on ObjC2 as well.

[analyzer] Fix a false positive in the ivar invalidation checker.

When a property is "inherited" through both a parent class and directly
through a protocol, we should not require the child to invalidate it
since the backing ivar belongs to the parent class.

[analyzer] Fix a false positive in Secure Keychain API checker.

Better handle the blacklisting of known bad deallocators when symbol
escapes through a call to CFStringCreateWithBytesNoCopy.

Pull the bulk of Lexer::MeasureTokenLength() out into a new function,
Lexer::getRawToken().

No functionality change.

[PCH] (De)serialize the end location of MacroInfo.

[libclang] When getting the cursor for an identifier inside a macro definition, check if
this was ever a macro name and return a specific CXCursor_MacroExpansion cursor in such a case,
instead of the generic CXCursor_MacroDefinition.

Checking for macro name makes sure the identifier is not part of the identifier list in a
function macro.
While, in general, resolving identifiers in macro definitions to other macros may not be completely accurate,
it greatly improves functionality such as give-me-the-definition-of-this, which was not working at all
inside macro definitions.

[libclang] Make token annotation of type/storage qualifiers accurate.

Previously type/storage qualifiers would not be annotated as the declaration they belonged to.
Just use the resulting source range of getRawCursorExtent() which is more correct
than what AnnotateTokensWorker::Visit() was adjusting it to.

[libclang] Simplify annotation of preprocessing tokens and remove the AnnotateTokensData
DenseMap and the lookups associated with it.

Instead of lexing for preprocessor tokens, associating the annotation with the location in a map,
and later lookup in the map in order to adjust the cursor annotation, just annotate the cursor
while lexing for preprocessor tokens.

[libclang] When annotating preprocessor tokens, if we are in a macro definition,
check if the token was ever a macro name and annotate it if that's the case.
