John McCall 0ad166672f Track source information for template arguments and template specialization
types.  Preserve it through template instantiation.  Preserve it through PCH,
although TSTs themselves aren't serializable, so that's pretty much meaningless.

Rafael Espindola 177f1d979d Split AddDefaultSystemIncludePaths into C, C++ and framework specific functions.
The user visible changes are:

*) Frameworks are only searched on OS X
*) The Cygwin c++ headers are now marked as c++ aware. I am almost
sure that not marking them was a bug.

John McCall 703a3f8a7b Preserve type source information in TypedefDecls. Preserve it across
template instantiation.  Preserve it through PCH.  Show it off to the indexer.

I'm healthily ignoring the vector type cases because we don't have a sensible
TypeLoc implementation for them anyway.

John McCall 856bbea332 Remove OriginalTypeParmDecl; the original type is the one specified
in the DeclaratorInfo, if one is present.

Preserve source information through template instantiation.  This is made
more complicated by the possibility that ParmVarDecls don't have DIs, which
is possibly worth fixing in the future.

Also preserve source information for function parameters in ObjC method
declarations.

Douglas Gregor 4bd90e53c2 Eliminate QualifiedDeclRefExpr, which captured the notion of a
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g., 

  namespace N { int i; }
  int j = N::i;

Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.

Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

Ted Kremenek 49c5232d9f Fix integer overflow in PCHReader when reading the length of an
identifier.  This caused a crash when reading PCH files that contained
long identifier names.

The issue is that 'StrLenPtr' was previously a 'const char *', meaning
the byte loaded from it would be interpretted as a signed integer.  If
the topmost bit was set, conversion to 'unsigned' would extend that
bit, causing an overflow.

The solution is to make 'StrLenPtr' an 'unsigned char *', always
treating the value as an unsigned integer.

This fixes: <rdar://problem/7328900>

John McCall fc93cf9777 When building types from declarators, instead of building two types (one for
the DeclaratorInfo, one for semantic analysis), just build a single type whose
canonical type will reflect the semantic analysis (assuming the type is
well-formed, of course).

To make that work, make a few changes to the type system:
* allow the nominal pointee type of a reference type to be a (possibly sugared)
  reference type.  Also, preserve the original spelling of the reference type.
  Both of these can be ignored on canonical reference types.
* Remove ObjCProtocolListType and preserve the associated source information on
  the various ObjC TypeLocs.  Preserve the spelling of protocol lists except in
  the canonical form.
* Preserve some level of source type structure on parameter types, but
  canonicalize on the canonical function type.  This is still a WIP.

Drops code size, makes strides towards accurate source location representation,
slight (~1.7%) progression on Cocoa.h because of complexity drop.

Ted Kremenek 428c637ada The constructor for ASTUnit now takes a DiagnosticClient*, allowing uses of ASTUnit to specify
alternate DiagnosticClients. To match this API, ASTUnit::LoadFromPCHFile() now takes a corresponding
DiagnosticClient* argument as well. The DiagnosticClient object is destroyed when the ASTUnit object
is destroyed.

The CIndex library now uses this API to create a 'IgnoreDiagnosticsClient' that simply silences
diagnostics when using the clang_createTranslationUnitFromSourceFile() function. This fixes
<rdar://problem/7312058>. This API can change in the future as we add more flexibility for clients.

John McCall cebee16bc0 When performing template-substitution into a type, don't just replace the
TemplateTypeParmType with the substituted type directly;  instead, replace it
with a SubstTemplateTypeParmType which will note that the type was originally
written as a template type parameter.  This makes it reasonable to preserve
source information even through template substitution.

Also define the new SubstTemplateTypeParmType class, obviously.

For consistency with current behavior, we stringize these types as if they
were the underlying type.  I'm not sure this is the right thing to do.
At any rate, I paled at adding yet another clause to the don't-desugar 'if'
statement, so I extracted a function to do it.  The new function also does
The Right Thing more often, I think:  e.g. if we have a chain of typedefs
leading to a vector type, we will now desugar all but the last one.

TypeLoc class names to be $(Type classname)Loc.  Rewrite the visitor.
Provide skeleton implementations for all the new TypeLocs.

It should be extremely straightforward to add new location information

Douglas Gregor 12bfa3859d Merge the "types" and "declarations" blocks in the precompiled header
format, so that we don't end up with multiple declaration and types
blocks. Also, fix a few obscure bugs with PCH loading and generation:

  - If the DeclIDs DenseMap reallocates while we are writing a
    declaration (due to recursively writing other declarations), we
    could end up writing a bad ID to ExternalDefinitions.
  - When loading an ArrayLoc (part of DeclaratorInfo), we need to set
    the size expression to NULL if no size expression was provided.

PCH -> AST rewriting is still partly broken, unfortunately.

Douglas Gregor 16bef857d9 Keep track of whether declararions were loaded from a precompiled
header or not via a new "PCHLevel" field in Decl. We currently use
this information to help CIndex filter out declarations that came from
a precompiled header (rather than from an AST file). Further down the
road, it can be used to help implement multi-level precompiled
headers.

Douglas Gregor d2eb58abac Add support for a chain of stat caches in the FileManager, rather than
only supporting a single stat cache. The immediate benefit of this
change is that we can now generate a PCH/AST file when including
another PCH file; in the future, the chain of stat caches will likely
be useful with multiple levels of PCH files.

John McCall 33815690af Better living through metaprogramming. Create a base class which abstracts
most of the unsafe boilerplate out of TypeLoc.  Create a QualifiedLoc class
to represent the idea that we *might* start representing source locations
of qualifiers.  Dealing with qualifiers explicitly like this also lets us
efficiently ignore them in all the concrete cases.

This should make it obvious and easy to add new TypeLoc subclasses.
