c392f37ae8 Split DependentNameType into two types. DependentNameType represents the
case of an elaborated-type-specifier like 'typename A<T>::foo', and
DependentTemplateSpecializationType represents the case of an
elaborated-type-specifier like 'typename A<T>::template B<T>'.  The TypeLoc
representation of a DependentTST conveniently exactly matches that of an
ElaboratedType wrapping a TST.

Kill off the explicit rebuild methods for RebuildInCurrentInstantiation;
the standard implementations work fine because the nested name specifier
is computable in the newly-entered context.

75b960e5ee Alter the ExternalASTSource interface to permit by-name lookups. PCH continues to
bring in the entire lookup table at once.

Also, give ExternalSemaSource's vtable a home.  This is important because otherwise
any reference to it will cause RTTI to be emitted, and since clang is compiled
with -fno-rtti, that RTTI will contain unresolved references (to ExternalASTSource's
RTTI).  So this change makes it possible to subclass ExternalSemaSource from projects
compiled with RTTI, as long as the subclass's home is compiled with -fno-rtti.

8b07ec253d Substantially alter the design of the Objective C type AST by introducing
ObjCObjectType, which is basically just a pair of
  one of {primitive-id, primitive-Class, user-defined @class}
with
  a list of protocols.
An ObjCObjectPointerType is therefore just a pointer which always points to
one of these types (possibly sugared).  ObjCInterfaceType is now just a kind
of ObjCObjectType which happens to not carry any protocols.

Alter a rather large number of use sites to use ObjCObjectType instead of
ObjCInterfaceType.  Store an ObjCInterfaceType as a pointer on the decl rather
than hashing them in a FoldingSet.  Remove some number of methods that are no
longer used, at least after this patch.

By simplifying ObjCObjectPointerType, we are now able to easily remove and apply
pointers to Objective-C types, which is crucial for a certain kind of ObjC++
metaprogramming common in WebKit.

e03aa55bfd Add support for '-fgnu-keywords' and '-fasm' to Clang's driver. They are not
implemented precisely the same as GCC, but the distinction GCC makes isn't
useful to represent. This allows parsing code which uses GCC-specific keywords
('asm', etc.) without parsing in a fully GNU mode.

9507d46d62 Remove the capture, serialization, and deserialization of comment
ranges as part of the ASTContext. This code is not and was never used,
but contributes ~250k to the size of the Cocoa.h precompiled
header.

aae9224e49 Implement serialization and lazy deserialization of the preprocessing
record (which includes all macro instantiations and definitions). As
with all lay deserialization, this introduces a new external source
(here, an external preprocessing record source) that loads all of the
preprocessed entities prior to iterating over the entities.

The preprocessing record is an optional part of the precompiled header
that is disabled by default (enabled with
-detailed-preprocessing-record). When the preprocessor given to the
PCH writer has a preprocessing record, that record is written into the
PCH file. When the PCH reader is given a PCH file that contains a
preprocessing record, it will be lazily loaded (which, effectively,
implicitly adds -detailed-preprocessing-record). This is the first
case where we have sections of the precompiled header that are
added/removed based on a compilation flag, which is
unfortunate. However, this data consumes ~550k in the PCH file for
Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering
this detailed preprocessing information, so it's too expensive to turn
on by default. In the future, we should investigate a better encoding
of this information.

5712ebced0 Fix header-search problems with precompiled headers, where the
presence or absence of header map arguments when using the precompiled
header would cause Clang to get confused about which headers had
already been included/imported, along with their controlling
macros. The fundamental problem is that the serialization of the
header search information was relying on the UIDs of FileEntry objects
at PCH generation time and PCH load time to be equivalent, which
effectively means that we had to probe the same files in the same
order. Differing header map arguments caused an extra FileEntry
lookup, but it's easy to imagine other minor command-line arguments
triggering this problem.

Header-search information is now encoded along with the
source-location entry for a file, so that we register information
about a file's properties as a header at the same time we create the
FileEntry for that file.

Fixes <rdar://problem/7743243>.

e78aac41de Create a new InjectedClassNameType to represent bare-word references to the
injected class name of a class template or class template partial specialization.
This is a non-canonical type;  the canonical type is still a template 
specialization type.  This becomes the TypeForDecl of the pattern declaration,
which cleans up some amount of code (and complicates some other parts, but
whatever).

Fixes PR6326 and probably a few others, primarily by re-establishing a few
invariants about TypeLoc sizes.

35351a9554 Add VarDecl::isThisDeclarationADefinition(), which properly encapsulates the logic for when a variable declaration is a (possibly tentativ) definition. Add a few functions building on this, and shift C tentative definition handling over to this new functionality. This shift also kills the Sema::TentativeDefinitions map and instead simply stores all declarations in the renamed list. The correct handling for multiple tentative definitions is instead shifted to the final walk of the list.

18e066f6a9 (1) Rename getClangSubversionRevision() to getClangRevision(), and
have it return a StringRef instead of an integer (to be more VCS
    agnostic).

(2) Add getClangFullRepositoryVersion(), which contains an
    amalgamation of the repository name and the revision.

(3) Change PCH to only emit the string returned by
    getClangFullRepositoryVersion() instead of also emitting the value
    of getClangSubversionRevision() (which has been removed).  This is
    functionally equivalent.

More cleanup to version string generation pending...
