If expensive checks are enabled, safe mode of libstdc++ is enabled too.
In this mode the library uses more complex data that allow additional
checks, for instance, a container may keep list of iterators that points
to it. If a code crashes it can leave these complex library objects in
inconsistent state. It occurs in a few tests that check error recovery
if compiler crashes. These test hang in expensive check mode, as the
library tries to synchronize access to the iterators pointing to some
container, but corresponding mutex remains locked after the crash.

This fix marks these tests as unsupported if clang is built with
libstdc++ safe mode enabled.

In such a case, as when using the NS_ENUM macro, for indexing purposes treat the typedef as 'transparent',
meaning we treat its references as symbols of the underlying tag symbol.
Also provide a libclang API to check for such typedefs.

Under this defect resolution, the injected-class-name of a class or class
template cannot be used except in very limited circumstances (when declaring a
constructor, in a nested-name-specifier, in a base-specifier, or in an
elaborated-type-specifier). This is apparently done to make parsing easier, but
it's a pain for us since we don't know whether a template-id using the
injected-class-name is valid at the point when we annotate it (we don't yet
know whether the template-id will become part of an elaborated-type-specifier).

As a tentative resolution to a perceived language defect, mem-initializer-ids
are added to the list of exceptions here (they generally follow the same rules
as base-specifiers).

When the reference to the injected-class-name uses the 'typename' or 'template'
keywords, we permit it to be used to name a type or template as an extension;
other compilers also accept some cases in this area. There are also a couple of
corner cases with dependent template names that we do not yet diagnose, but
which will also get this treatment.

properly even when a non-type template parameter has a dependent type.

Previously, if a non-type template parameter was dependent, but not dependent
on an outer level of template parameter, we would not match the type of the
parameter. Under [temp.arg.template], we are supposed to check that the types
are equivalent, which means checking for syntactic equivalence in the dependent
case.

This also fixes some accepts-invalids when passing templates with auto-typed
non-type template parameters as template template arguments.

Now when completing blocks properties that return void the block call completion
result shows up before the setter, otherwise the setter completion shows up
before the block call completion. We normally want to use the result of the
block call, so one typically wouldn't call a block that returns a non-void type
in a standalone statement.
