Alex Lorenz 76377dcf99 Print nested name specifiers for typedefs and type aliases
Printing typedefs or type aliases using clang_getTypeSpelling() is missing the
namespace they are defined in. This is in contrast to other types that always
yield the full typename including namespaces.

Richard Smith d7279bba20 Update C++ status pages for Clang 4 branch:
* Update version number in DR tests from 4.0 to 4
 * Teach make_cxx_dr_status script about version numbers that don't contain a
   period.
 * Update cxx_status.html and cxx_dr_status.html to list Clang 4 features as
   "Clang 4" rather than "SVN"

Clang 4 features are still listed in yellow rather than green until release.

Reid Kleckner 1a4ab7e772 Improve error message when referencing a non-tag type with a tag
Other compilers accept invalid code here that we reject, and we need a
better error message to try to convince users that the code is really
incorrect. Consider:
  class Foo {
    typedef MyIterHelper<Foo> iterator;
    friend class iterator;
  };

Previously our wording was "elaborated type refers to a typedef".
"elaborated type" isn't widely known terminology, so the new diagnostic
says "typedef 'iterator' cannot be referenced with class specifier".

Richard Smith 82da19ddb3 [c++1z] P0003R5: Removing dynamic exception specifications.
We continue to support dynamic exception specifications in C++1z as an
extension, but produce an error-by-default warning when we encounter one. This
allows users to opt back into the feature with a warning flag, and implicitly
opts system headers back into the feature should they happen to use it.

There is one semantic change implied by P0003R5 but not implemented here:
violating a throw() exception specification should now call std::terminate
directly instead of calling std::unexpected(), but since P0003R5 also removes
std::unexpected() and std::set_unexpected, and the default unexpected handler
calls std::terminate(), a conforming C++1z program cannot tell that we are
still calling it. The upside of this strategy is perfect backwards
compatibility; the downside is that we don't get the more efficient 'noexcept'
codegen for 'throw()'.

Richard Smith 3c4f8d2e96 P0012R1: Make exception specifications be part of the type system. This

exception specifications), but not all the details just yet.

Richard Smith e4caa48dbb DR259: Demote the pedantic error for an explicit instantiation after an
explicit specialization to a warning for C++98 mode (this is a defect report
resolution, so per our informal policy it should apply in C++98), and turn
the warning on by default for C++11 and later. In all cases where it fires, the
right thing to do is to remove the pointless explicit instantiation.

Richard Smith 410cc89374 [c++1z] Most of N4268 (allow constant evaluation for non-type template arguments).
We don't yet support pointer-to-member template arguments that have undergone
pointer-to-member conversions, mostly because we don't have a mangling for them yet.

Richard Smith 0daabd7ebe Don't perform ADL when looking up operator=; there is no non-member form of
that function, and apart from being slow, this is unnecessary: ADL can trigger
instantiations that are not permitted here. The standard isn't *completely*
clear here, but this seems like the intent, and in any case this approach is
permitted by [temp.inst]p7.

Richard Smith 091405d7e3 Reword switch/goto diagnostics "protected scope" diagnostics. Making up a term
"protected scope" is very unhelpful here and actively confuses users. Instead,
simply state the nature of the problem in the diagnostic: we cannot jump from
here to there. The notes explain nicely why not.

Hans Wennborg 3d79154aec [Win32 ABI] Defer operator delete checks until vtable is marked used
We were previously checking at every destructor declaration, but that was a bit
excessive. Since the deleting destructor is emitted with the vtable, do the
check when the vtable is marked used.

Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag.
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.
