argument but doesn't (because previous template parameters had default
arguments), clear out all of the default arguments so that we maintain
the invariant that a template parameter has a default argument only if
subsequence template parameters also have default arguments.

derived-to-base cast that also casts away constness (one of the cases
for static_cast followed by const_cast) would be treated as a bit-cast
rather than a derived-to-base class, causing miscompiles and
heartburn.

rvalue references for *this.

reference binding is for the implicit object parameter of a member
function with a ref-qualifier. My previous comment, that we didn't
need to track this explicitly, was wrong: we do in fact get
rvalue-references-prefer-rvalues overloading with ref-qualifiers.

a ref-qualifier (C++0x [over.match.funcs]p4).

the presence and form of a ref-qualifier. Note that we do *not* yet
implement the restriction in C++0x [over.load]p2 that requires either
all non-static functions with a given parameter-type-list to have a
ref-qualifier or none of them to have a ref-qualifier.

using rules that I just made up this morning. This encoding has now
been proposed to the Itanium C++ ABI group for inclusion, but of
course it's still possible that the mangling will change.

  - Don't publicize a C++0x feature through __has_feature if we aren't
    in C++0x mode (even if the feature is available only with a
    warning). 
  - "auto" is not implemented well enough for its __has_feature to be
    turned on.
  - Fix the test of C++0x __has_feature to actually test what we're
  trying to test. Searching for the substring "foo" when our options
  are "foo" and "no_foo" doesn't work :)

  - Add ref-qualifiers to the type system; they are part of the
  canonical type. Print & profile ref-qualifiers
  - Translate the ref-qualifier from the Declarator chunk for
    functions to the function type. 
  - Diagnose mis-uses of ref-qualifiers w.r.t. static member
  functions, free functions, constructors, destructors, etc.
  - Add serialization and deserialization of ref-qualifiers.

after a 'return' in a CFGBlock.  This accidentally
was working before, but the false assumption that
'return' always appeared at the end of the block
was uncovered by a recent change.

a warning for uses of an uninitialized variable
when the use is a void cast, e.g. (void) x.

I'm separately committing this because it incidentally changes some
block orderings and minor IR issues, like using a phi instead of
an unnecessary alloca.

handling all CFGElement kinds.  While writing
the test case, it turned out that return-noreturn.cpp
wasn't actually testing anything since it has the wrong -W
flag.  That uncovered another regression with
the handling of destructors marked noreturn.  WIP.
