This commit implements basic support for indexing of dependent declaration
references. Now the indexer tries to find a suitable match in the base template
for a dependent member ref/decl ref/dependent type.

delayed diagnostic
This fix avoids an infinite recursion that was uncovered in one of our internal
tests by r301992. The testcase is the most reduced version of that
auto-generated test.
This is an improved version of the reverted commit r302037. The previous fix
actually managed to expose another subtle bug whereby `fatal_too_many_errors`
error was reported twice, with the second report setting the
`FatalErrorOccurred` flag. That prevented the notes that followed the diagnostic
the caused `fatal_too_many_errors` to be emitted. This commit ensures that notes
that follow `fatal_too_many_errors` but that belong to the diagnostic that
caused `fatal_too_many_errors` won't be emitted by setting the
`FatalErrorOccurred` when emitting `fatal_too_many_errors`.

specializations that 'override' declarations in the base template should use
the 'specializationOf' relation instead of 'specializationOf | overrideOf'.
The indexer relations are meant to be orthogonal, so 'specializationOf' is
better than the combined relation.

The intent for an explicit module build is that the diagnostics produced within
the module are those that were configured when the module was built, not those
that are enabled within a user of the module. This includes diagnostics that
don't actually show up until the module is used (for instance, diagnostics
produced during template instantiation and weird cases like -Wpadded).
We serialized and restored the diagnostic state for individual warning groups,
but previously did not track the state for flags like -Werror and -Weverything,
which are implemented as separate bits rather than as part of the diagnostics
mapping information.

This allows users to query the target triple and target pointer width, which
would make me able to fix https://github.com/servo/rust-bindgen/issues/593 and
other related bugs in an elegant way (without having to manually parse the
target triple in the command line arguments).

This can be used for improved "go to definition" feature in Xcode.

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.

This enhances the AST to keep track of locations of the names in those ObjC property attributes, and reports them for indexing.

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.

Report the typedef as reference, and desugar it to report the underlying class as an
implicit 'base' reference.
Reporting the underlying base class for 'base' relations matches the ObjC handling and
leads to a simpler model.

Parameters have a 'child' relation to their function/method.
Also add an option '-include-locals' to 'c-index-test core' to enable indexing of function-local symbols.

This get the resource dir string to match with the one from libclang (which is not adding '/../'),
and allows clang to accept a modules-enabled PCH that was created by libclang.

Related synthesized properties with the ivar they use with the 'accessor' relation, and make sure
we mark them 'implicit' when appropriate.

If the preamble had diagnostic state this would leave behind invalid
state in the DiagnosticsEngine and crash later. The test case runs into
an assertion in DiagnosticsEngine::setSourceManager.

Expose the half type (fp16) through libclang and the python bindings.
It seems CXType_LastBuiltin was not updated in b2ea6d9 ("Enable
support for __float128 in Clang", 2016-04-13), so update it now.
Add an Index test for OpenCL types; in the future we will add other
OpenCL types such as images to this test.
