Douglas Gregor e442fe3db9 Make sure we initialize the "extra" data within the libclang code
completion context, in case we end up having no code-completion
callback. Individual instances of this problem are always bugs that
need to be fixed, but it's better to make sure we have initialized
data here.

Ted Kremenek 5b8ad40664 [libclang] Workaround potential race condition with code completion AllocatedResults being freed after a CXTranslationUnit.
The Container USR's CXString had its underlying data owned by the CXTranslationUnit's string pool.  This
would result in trying to access freed memory.

Douglas Gregor 2c595adf2e When performing code completion after at @interface, allow both
already-defined and forward-declared results. Already-defined results
are fine because they could be the start of a category. Fixes

Ted Kremenek 5e14d39a88 Improve crash recovery cleanup to recovery CompilerInstances during crash recovery. This was a huge resource "root" during crashes.
This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct
ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance
object.

Douglas Gregor 162b712d38 Teach the CXCodeCompleteResults results structure, which stores
code-completion results accessed via libclang, to extend the lifetime
of the allocator used for cached global code-completion results at

Douglas Gregor b278aafbfb Allocate CodeCompletionString and all of its components in a
BumpPtrAllocator, rather than manually new/delete'ing them. This
optimization also allows us to avoid allocating memory for and copying
constant strings (e.g., "return", "class").

This also required embedding the priority and availability of results
within the code completion string, to avoid extra memory allocation
within libclang.

Chris Lattner 5159f6162e now the FileManager has a FileSystemOpts ivar, stop threading
FileSystemOpts through a ton of apis, simplifying a lot of code.
This also fixes a latent bug in ASTUnit where it would invoke
methods on FileManager without creating one in some code paths
in cindextext.

Argyrios Kyrtzidis d004064864 Refactoring of Diagnostic class.
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class.
-DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units.
-The rest of the state in Diagnostic object is considered related and tied to one translation unit.
-Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a
   SourceLocation instead of a FullSourceLoc.
-Reflect the changes to various interfaces.

Douglas Gregor 68dbaead7b Fix source-range information for Objective-C properties. Previously,
we were just getting a range covering only the property name, which is
certainly not correct (and broke token annotation, among other
things). 

Also, teach libclang about the relationship between
@synthesize/@dynamic and @property, so we get property name and
cursor-reference information for @synthesize and @dynamic.

Ted Kremenek 915542850b Change CXTranslationUnit to not directly cast to an ASTUnit*,
but to wrap both an ASTUnit and a "string pool"
that will be used for fast USR generation.

This requires a bunch of mechanical changes, as
there was a ton of code that assumed that CXTranslationUnit
and ASTUnit* were the same.

Along with this change, introduce CXStringBuf,
which provides an llvm::SmallVector<char> backing
for repeatedly generating CXStrings without a huge
amount of malloc() traffic.  This requires making
some changes to the representation of CXString
by renaming a few fields (but keeping the size
of the object the same).

Argyrios Kyrtzidis 71731d6b05 Implement -working-directory.
When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.

--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
 the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
 file operations will be abstracted in the future for the reproduction mechanism.

FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

Addresses rdar://8583824.

Douglas Gregor 8e3e8743fb Introduce code completion results for Objective-C methods, both when
declaring methods and when sending messages to them, by bringing all
of the selector into TypedCheck chunks in the completion result. This
way, we can improve the sorting of these results to account for the
full selector name rather than just the first chunk.

Douglas Gregor 36e3b5c79e Switch c-index-test from clang_codeComplete() over to
clang_codeCompleteAt(). This uncovered a few issues with the latter:

  - ASTUnit wasn't saving/restoring diagnostic state appropriately between
    reparses and code completions.
  - "Overload" completions weren't being passed through to the client
