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.

998d51b98f When "delayed parsing" C++ default arguments, if there is an error, there may be tokens left in the token stream
that will interfere (they will be parsed as if they are after the class' '}') and a crash will occur because
the CachedTokens that holds them will be deleted while the lexer is still using them.

Make sure that the tokens of default args are removed from the token stream.
Fixes PR6647.

8bc2a70dfe Don't infinite-loop if TryAnnotateCXXScopeToken fails to annotate but doesn't
signal an error.  This can happen even when the current token is '::' if
this is a ::new or ::delete expression.

This was an oversight in my recent parser refactor;  fixes PR 5825.

1f476a1783 Fix an assertion-on-error during tentative constructor parsing by
propagating error conditions out of the various annotate-me-a-snowflake
routines.  Generally (but not universally) removes redundant diagnostics
as well as, you know, not crashing on bad code.  On the other hand,
I have just signed myself up to fix fiddly parser errors for the next
week.  Again.

38200b081a Improve the diagnostic given when referring to a tag type without a tag (in C)
or that's been hidden by a non-type (in C++).

3ce7493c35 Teach C++ name lookup that it's okay to look in a scope without a
context. This happens fairly rarely (which is why we got away with
this bug). Fixes PR6184, where we skipped over the template parameter
scope while tentatively parsing.

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).

6e9f8f6374 Honor using declarations in overload resolution. Most of the code for
overloaded-operator resolution is wildly untested, but the parallel code for
methods seems to satisfy some trivial tests.

Also change some overload-resolution APIs to take a type instead of an expression,
which lets us avoid creating a spurious CXXThisExpr when resolving implicit
member accesses.
