LookupInObjCMethod. Doing so allows all sorts of invalid code
to slip through to codegen. This patch does not change the
AST representation of super, though that would now be a natural
thing to do since it can only be in the receiver position and
in the base of a ObjCPropertyRefExpr.
There are still several ugly areas handling super in the parser,
but this is definitely a step in the right direction.

typo correction. However, now that the code has been factored out
of LookupMemberExpr, it can recurse to itself instead of to
LookupMemberExpr! Remove grossness.

This is *much* uglier than it should be due to grossness in

when they're instantiated. Merge the note into the -Wreorder warning; it
doesn't really contribute much, and it was splitting a thought across diagnostics
anyway. Don't crash in the parser when a constructor's initializers end in a
comma and there's no body; the recovery here is still terrible, but anything's
better than a crash.

specializations when the explicit instantiation was... explicitly
written, i.e., not the product of an explicit instantiation of an
enclosing class. Fixes this spurious warning when Clang builds LLVM:

warning: explicit instantiation of 'addRoot' that occurs after an
explicit specialization will be ignored (C++0x extension) [-pedantic]

we don't have enough information to tell them how to use 'strncmp'. Instead, change the
diagnostic to indicate they should use 'strncmp'.

the implicit template instantiations we need to perform. Otherwise, we
end up erroneously diagnosing static functions as used if they were
only used within an implicit template instantiation. Fixes a bunch of
spurious failures when building Clang with Clang.

destination type for initialization, assignment, parameter-passing,
etc. The main issue fixed here is that we used rather confusing
wording for diagnostics such as
t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
expected 'char *' [-pedantic]
char *name = __func__;
^ ~~~~~~~~
We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:
t.c:2:9: warning: initializing 'char *' from an expression of type
'char const [2]' discards qualifiers [-pedantic]
char *name = __func__;
^ ~~~~~~~~

provides an inconsistent warnings experience for the user and that there were
genuine cases where we wouldn't want to do this optimization.

<tr1/hashtable> header, where a friend class template
std::tr1::__detail::_Map_base is declared with the wrong template

back-flip to avoid diagnosing just this one instance of the problem.

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
