This is a new upstream library that exports both the clang and LLVM C++
symbols and can replace libLLVM and (android-toolchain-only)
libclang_cxx.so.

I've removed check-symbols.py because that's been broken for years and
we never even noticed, and I'm not sure it's worth fixing.

If we remove the mips uapi headers, versioner fails because it assumes
they're available. We'll need a new versioner prebuilt beforre we can
remove the libc/versioner-dependencies/mips* symlinks.

This commit adds versioner_fortify_inline annotation. This annotation
indicates that the annotated function is an overloaded inline function
for _FORTIFY_SOURCE implementation. They are usually enabled/disabled
by the enable_if attribute, thus the versioner don't have to check
whether they have conflicting definitions.

This commit adds a built-in macro for conditional compilation because
__attribute__((annotate(...))) may pull unused static inline functions
into object files.
We must not generate those functions in object files because it can
result in undefined references to __strchr_chk on linux_glibc.

This commit replaces `clang::driver::ArgStringList` with
`llvm::opt::ArgStringList` because starting from r344398, the alias for
`llvm::opt::ArgStringList` has been removed from the `clang::driver`
namespace.
Note: This is a step to port clang tools to clang-r346389.

C++17 removed a handful of things that are used in the libclang
headers, which are used by the versioner. Enable the flag that
re-exposes these until we have a C++17 compatible libclang.

extern "C" and "C++" are parsed as a LinkageSpecDecl with the real Decl
as a child node. This leads to the preprocessor sticking its guard
between the extern specifier and the declaration.
Update the AST visitor to add a special-case for calculating the
SourceRange on a LinkageSpecDecl, and add a test.

GCC's FORTIFY required optimizations to be enabled in order to function
properly. Clang's FORTIFY doesn't have this limitation, so it seems
pointless to keep it disabled due to a GCC-specific limitation.

This patch cleans up our standard headers by moving most of the FORTIFY
cruft out in to its own sandbox. In order to include the *_chk and
*_real declarations, you can either enable FORTIFY, or `#define
__BIONIC_DECLARE_FORTIFY_HELPERS`.
Both sys/select.h and strings.h are explicitly ignored by this patch.
Both of these files have very small __BIONIC_FORTIFY blocks, and don't
define any actual FORTIFY'ed functions (just macros, and 3 *_chk
functions).
This patch also makes the versioner ignore the FORTIFY implementation
headers, since we're guaranteed to pick the FORTIFY'ed headers up when
looking at the regular headers. (...Not to mention that making the
FORTIFY'ed headers freestanding would be annoying to do and maintain for
~no benefit).
We bake the knowledge of where FORTIFY headers live directly into the
versioner. We could go with a more general approach (e.g. adding an -X
IGNORED_FILE flag that tells the versioner to ignore
$HEADER_PATH/$IGNORED_FILE), but we'd then have to repeat that for every
test, every manual invocation of the versioner, etc. for no benefit
that's obvious to me.
