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).

379d84b7ed When performing copy initialization (= "implicit conversion", here) to
a class type from itself or a derived class thereof, enumerate
constructors and permit user-defined conversions to the arguments of
those constructors. This fixes the wacky implicit conversion sequence
used in std::auto_ptr's lame emulation of move semantics.

resolution of type conversion functions in base and
current class.

1b12ed4a00 Perform the C++ specific semantic checks of a function declaration after it's been merged with the previous declaration. This ensures that getPreviousDecl() will have the right value when ActOnConversionDeclarator is called.

1a99f441e6 Fix a crash bug when comparing overload quality of conversion operators with conversion constructors.
Remove an atrocious amount of trailing whitespace in the overloaded operator mangler. Sorry, couldn't help myself.
Change the DeclType parameter of Sema::CheckReferenceInit to be passed by value instead of reference. It wasn't changed anywhere.
Let the parser handle C++'s irregular grammar around assignment-expression and conditional-expression.
And finally, the reason for all this stuff: implement C++ semantics for the conditional operator. The implementation is complete except for determining lvalueness.

Tests and drivers updated, still need to shuffle dirs.

b8a9a41dd6 Fix our semantic analysis of
unqualified-id '('

in C++. The unqualified-id might not refer to any declaration in our
current scope, but declarations by that name might be found via
argument-dependent lookup. We now do so properly.

As part of this change, CXXDependentNameExpr, which was previously
designed to express the unqualified-id in the above constructor within
templates, has become UnresolvedFunctionNameExpr, which does
effectively the same thing but will work for both templates and
non-templates.

Additionally, we cope with all unqualified-ids, since ADL also applies
in cases like

  operator+(x, y)

0369c57ac6 Make all the 'redefinition' diagnostics more consistent, and make the
"previously defined here" diagnostics all notes.

4ea8043d6f As threatened previously: consolidate name lookup and the creation of
DeclRefExprs and BlockDeclRefExprs into a single function
Sema::ActOnDeclarationNameExpr, eliminating a bunch of duplicate
lookup-name-and-check-the-result code.

Note that we still have the three parser entry points for identifiers,
operator-function-ids, and conversion-function-ids, since the parser
doesn't (and shouldn't) know about DeclarationNames. This is a Good
Thing (TM), and there will be more entrypoints coming (e.g., for C++
pseudo-destructor expressions).

92751d41a0 Eliminate all of the placeholder identifiers used for constructors,
destructors, and conversion functions. The placeholders were used to
work around the fact that the parser and some of Sema really wanted
declarators to have simple identifiers; now, the code that deals with
declarators will use DeclarationNames.

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.

dbc5daf058 Parsing, ASTs, and semantic analysis for the declaration of conversion
functions in C++, e.g.,

  struct X {
    operator bool() const;
  };

Note that these conversions don't actually do anything, since we don't
yet have the ability to use them for implicit or explicit conversions.
