John McCall 1700197e65 Clone the full Type hierarchy into the TypeLoc hierarchy. Normalize
TypeLoc class names to be $(Type classname)Loc.  Rewrite the visitor.
Provide skeleton implementations for all the new TypeLocs.

Handle all cases in PCH.  Handle a few more cases when inserting
location information in SemaType.

It should be extremely straightforward to add new location information
to existing TypeLoc objects now.

Daniel Dunbar 19a203965f Remove a FIXME that doesn't belong, there are numerous other places that use
alignment in bits in clang. If we really want to fix this, it should be a bugzilla.

Daniel Dunbar cc2f79b44b Add IdentiferInfo::getNameStr() -> StringRef.
Also, add getNameStart as a synonym for getName(). getName() is now deprecated,
when all clients are updated then getNameStr() should be renamed to
getName(). PR5218.

Ted Kremenek 8bcb1c6883 Add 'UseBumpPtrAllocator' flag to ASTUnit::LoadFromPCHFile() to cause the created ASTContext to use
its own BumpPtrAllocator to allocate ASTs.

Change clang_createTranslationUnit (CIndex) to pass 'UseBumpPtrAllocator = true' to
ASTUnit::LoadFromPCHFile().

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 c5b8225285 Remove the ConstantArrayType subtypes. This information is preserved in the
TypeLoc records for declarations;  it should not be necessary to represent it

previous functionality using the TypeLoc API.

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.

Chris Lattner 4f8a2e22c0 fix some cfstring related issues:
1) -fwritable-string does affect the non-utf16 version of cfstrings
   just not the utf16 ones.
2) utf16 strings should always be marked constant, as the __TEXT segment
   is readonly.
3) The name of the global doesn't matter, remove it from TargetInfo.
4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now.

This fixes rdar://7115750

Douglas Gregor 15e5602e59 Improve diagnostics when the parser encounters a declarator with an
unknown type name, e.g.,

  foo::bar x;

when "bar" does not refer to a type in "foo". 

With this change, the parser now calls into the action to perform
diagnostics and can try to recover by substituting in an appropriate
type. For example, this allows us to easily diagnose some missing
"typename" specifiers, which we now do:

  test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename'
        prior to dependent type name 'A<T>::type'
  A<T>::type A<T>::f() { return type(); }
  ^~~~~~~~~~
  typename

what we found when we looked into <blah>", where <blah> is a

"namespace N", "the global namespace", "'class Foo'".

This is part of PR3990, but we're not quite there yet.

Douglas Gregor cf91555cb8 When explicitly specializing a member that is a template, mark the
template as a specialization. For example, this occurs with:

  template<typename T>
  struct X {
    template<typename U> struct Inner { /* ... */ };
  };

  template<> template<typename T>
  struct X<int>::Inner {
    T member;
  };

We need to treat templates that are member specializations as special
in two contexts:

  - When looking for a definition of a member template, we look
    through the instantiation chain until we hit the primary template
    *or a member specialization*. This allows us to distinguish
    between the primary "Inner" definition and the X<int>::Inner
    definition, above.
  - When computing all of the levels of template arguments needed to
    instantiate a member template, don't add template arguments
    from contexts outside of the instantiation of a member
    specialization, since the user has already manually substituted
    those arguments.

Fix up the existing test for p18, which was actually wrong (but we
didn't diagnose it because of our poor handling of member
specializations of templates), and add a new test for member
specializations of templates.

Douglas Gregor 3a88c1d784 Improve the internal representation and semantic analysis of friend
function templates.

This commit ensures that friend function templates are constructed as
FunctionTemplateDecls rather than partial FunctionDecls (as they
previously were). It then implements template instantiation for friend
function templates, injecting the friend function template only when
no previous declaration exists at the time of instantiation. 

Oh, and make sure that explicit specialization declarations are not
friends.
