John McCall 3155f573f5 Turn access control on by default in -cc1.
Remove -faccess-control from -cc1; add -fno-access-control.
Make the driver pass -fno-access-control by default.
Update a bunch of tests to be correct under access control.

Douglas Gregor 3b4abb6792 Improve handling of friend types in several ways:
- When instantiating a friend type template, perform semantic
  analysis on the resulting type.
  - Downgrade the errors concerning friend type declarations that do
  not refer to classes to ExtWarns in C++98/03. C++0x allows
  practically any type to be befriended, and ignores the friend
  declaration if the type is not a class.

John McCall ef01f71a5a Pretty-print anonymous types using their kind and presumed location.

John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

Chandler Carruth f50ef6ed9a Make Decl::isOutOfLine() virtual, and use that to determine when definitions
are for out of line declarations more easily. This simplifies the logic and
handles the case of out-of-line class definitions correctly. Fixes PR6107.

John McCall 5b0829a321 Improve access control diagnostics. Perform access control on member-pointer
conversions.  Fix an access-control bug where privileges were not considered
at intermediate points along the inheritance path.  Prepare for friends.

Eli Friedman 7827520ce8 Initialization improvements: addition of string initialization and a few
small bug fixes in SemaInit, switch over SemaDecl to use it more often, and
change a bunch of diagnostics which are different with the new initialization
code.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

John McCall cd4b47747b Stop trying to analyze class-hierarchies for dependently-scoped id-expressions;
there's nothing interesting we can say now that we're correctly not requiring
the qualifier to name a known base class in dependent contexts.

Require scope specifiers on member access expressions to name complete types
if they're not dependent;  delay lookup when they are dependent.

Use more appropriate diagnostics when qualified implicit member access
expressions find declarations from unrelated classes.

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 

Fixes PR3990.

Douglas Gregor 3dad842b35 Rework the Parse-Sema interaction for friends to better support friend
class templates. We now treat friend class templates much more like
normal class templates, except that they still get special name lookup
rules. Fixes PR5057 and eliminates a bunch of spurious diagnostics in
<iostream>.

John McCall e94dd7ccf5 When adding a friend class declaration to the lookup tables, use the access specifier
of any previous declaration in case we replace it in a class's declaration table.
Fixes bug 4858.  This sort of thing makes me reconsider putting friend declarations in
declaration lists.

John McCall 2dc078f24e Ensure that the tag decls of friend decls aren't added to the friending class's
decl list, and remove some workarounds that were due to this.  Thanks to Eli for
pointing this out and providing the test case.

John McCall aa74a0c3b5 Omnibus friend decl refactoring. Instead of cloning AST classes for friend
declarations of same, introduce a single AST class and add appropriate bits
(encoded in the namespace) for whether a decl is "real" or not.  Much hackery
about previously-declared / not-previously-declared, but it's essentially
mandated by the standard that friends alter lookup, and this is at least
fairly non-intrusive.

Refactor the Sema methods specific to friends for cleaner flow and less nesting.

Incidentally solve a few bugs, but I remain confident that we can put them back.

are enabled (and even when they aren't, only give an extwarn about it).
