Owen Anderson 029eb7d243 Clarify the documentation of ext_vector, and add a small example. Hopefully 
this will alleviate some confusion about the existence of this feature.

Comments/improvements welcome.

Alexis Hunt af4e28d897 Add a bunch more feature-checking macros for C++0x features. Some of these are 
disabled with the intent that users can start with them now and not have to change
a thing to have them work when we implement the features.

Douglas Gregor 0086a5a3bb Introduce the notion of "Relocatable" precompiled headers, which are built 
with a particular system root directory and can be used with a different
system root directory when the headers it depends on have been installed.
Relocatable precompiled headers rewrite the file names of the headers used
when generating the PCH file into the corresponding file names of the 
headers available when using the PCH file.

Addresses <rdar://problem/7001604>.

Chris Lattner b6f77af532 implement and document a new __has_feature and __has_builtin magic 
builtin preprocessor macro.  This appears to work with two caveats:
1) builtins are registered in -E mode, and 2) target-specific builtins
are unconditionally registered even if they aren't supported by the
target (e.g. SSE4 builtin when only SSE1 is enabled).

Douglas Gregor 7f74112756 Implement parsing of nested-name-specifiers that involve template-ids, e.g., 
std::vector<int>::allocator_type

When we parse a template-id that names a type, it will become either a
template-id annotation (which is a parsed representation of a
template-id that has not yet been through semantic analysis) or a
typename annotation (where semantic analysis has resolved the
template-id to an actual type), depending on the context. We only
produce a type in contexts where we know that we only need type
information, e.g., in a type specifier. Otherwise, we create a
template-id annotation that can later be "upgraded" by transforming it
into a typename annotation when the parser needs a type. This occurs,
for example, when we've parsed "std::vector<int>" above and then see
the '::' after it. However, it means that when writing something like
this:

  template<> class Outer::Inner<int> { ... };

We have two tokens to represent Outer::Inner<int>: one token for the
nested name specifier Outer::, and one template-id annotation token
for Inner<int>, which will be passed to semantic analysis to define
the class template specialization.

Most of the churn in the template tests in this patch come from an
improvement in our error recovery from ill-formed template-ids.

Douglas Gregor 94349fd8cb Allow "overloadable" functions in C to be declared as variadic without 
any named parameters, e.g., this is accepted in C:

  void f(...) __attribute__((overloadable));

although this would be rejected:

  void f(...);

To do this, moved the checking of the "ellipsis without any named
arguments" condition from the parser into Sema (where it belongs anyway).

Douglas Gregor 2ada048975 Some name-lookup-related fixes, from Piotr Rak! 
- Changes Lookup*Name functions to return NamedDecls, instead of
Decls. Unfortunately my recent statement that it will simplify lot of
code, was not quite right, but it simplifies some...
- Makes MergeLookupResult SmallPtrSet instead of vector, following
Douglas suggestions.
- Adds %qN format for printing qualified names to Diagnostic.
- Avoids searching for using-directives in Scopes, which are not
DeclScope, during unqualified name lookup.

Since it doesn't return a bool, is shouldn't be prefixed with 'is'.

Douglas Gregor 6e6ad602e5 Remove ScopedDecl, collapsing all of its functionality into Decl, so 
that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

Douglas Gregor 07665a69e8 Introduce support for "transparent" DeclContexts, which are 
DeclContexts whose members are visible from enclosing DeclContexts up
to (and including) the innermost enclosing non-transparent
DeclContexts. Transparent DeclContexts unify the mechanism to be used
for various language features, including C enumerations, anonymous
unions, C++0x inline namespaces, and C++ linkage
specifications. Please refer to the documentation in the Clang
internals manual for more information.

Only enumerations and linkage specifications currently use transparent
DeclContexts.

Still to do: use transparent DeclContexts to implement anonymous
unions and GCC's anonymous structs extension, and, later, the C++0x
features. We also need to tighten up the DeclContext/ScopedDecl link
to ensure that every ScopedDecl is in a single DeclContext, which
will ensure that we can then enforce ownership and reduce the memory
footprint of DeclContext.

Chris Lattner e4b95698df Rename Selector::getName() to Selector::getAsString(), and add 
a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.

Douglas Gregor 163c58502a Extend DeclarationName to support C++ overloaded operators, e.g., 
operator+, directly, using the same mechanism as all other special
names.

Removed the "special" identifiers for the overloaded operators from
the identifier table and IdentifierInfo data structure. IdentifierInfo
is back to representing only real identifiers.

Added a new Action, ActOnOperatorFunctionIdExpr, that builds an
expression from an parsed operator-function-id (e.g., "operator
+"). ActOnIdentifierExpr used to do this job, but
operator-function-ids are no longer represented by IdentifierInfo's.

Extended Declarator to store overloaded operator names. 
Sema::GetNameForDeclarator now knows how to turn the operator
name into a DeclarationName for the overloaded operator. 

Except for (perhaps) consolidating the functionality of
ActOnIdentifier, ActOnOperatorFunctionIdExpr, and
ActOnConversionFunctionExpr into a common routine that builds an
appropriate DeclRefExpr by looking up a DeclarationName, all of the
work on normalizing declaration names should be complete with this
commit.

Douglas Gregor ae2fbad373 Updated IdentifierResolver to deal with DeclarationNames. The names of 
C++ constructors, destructors, and conversion functions now have a
FETokenInfo field that IdentifierResolver can access, so that these
special names are handled just like ordinary identifiers. A few other
Sema routines now use DeclarationNames instead of IdentifierInfo*'s.

To validate this design, this code also implements parsing and
semantic analysis for id-expressions that name conversion functions,
e.g.,

  return operator bool();

The new parser action ActOnConversionFunctionExpr takes the result of
parsing "operator type-id" and turning it into an expression, using
the IdentifierResolver with the DeclarationName of the conversion
function. ActOnDeclarator pushes those conversion function names into
scope so that the IdentifierResolver can find them, of course.
