authors to write

when they want to force users to name all variables of the type. This protects
people from doing things like creating a scoped_lock that only lives for a
single statement instead of an entire scope.

The warning produced by this attribute can be disabled by

(C++0x [over.ics.rank]p3) when one binding is an lvalue reference and
the other is an rvalue reference that binds to an rvalue. In
particular, we were using the predict "is an rvalue reference" rather
than "is an rvalue reference that binds to an rvalue", which was
incorrect in the one case where an rvalue reference can bind to an
lvalue: function references.

This particular issue cropped up with std::forward, where Clang was
picking an std::forward overload while forwarding an (lvalue)
reference to a function. However (and unfortunately!), the right
answer for this code is that the call to std::forward is
ambiguous. Clang now gets that right, but we need to revisit the
std::forward implementation in libc++.

This assertion is too restrictive, it does not apply for dangling dbg value nodes (nodes where dbg.value intrinsic preceds use of the value).

this little tweak fixes PR8629, where bad location information slipped

Also change the test case from test_set_output_path to test_set_error_output_path

types. What was happening was the DWARF parser was almost ignoring definitions
(DIEs with the DW_AT_declaration set to 1). It wasn't ignoring declarations
that had _some_ children. When this happened, we would treat the declaration
as a complete type. Often we would have a declaration of a type with just
some enum definitions inside and nothing else. Now we correctly ignore these
definitions, and also I added some changes to allow us to figure out what
decl context these special declarations actually point to.
