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.
Add a stub posix_memalign to the linker. libc++abi uses posix_memalign
when allocating exceptions, which the linker does not use.

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.

After the new rebase of Clang, we now supports alloc_size attribute, so
we can remove the warning about switching to alloc_size once Clang has
support.

old rebase or the new rebase.

MemoryBuffer::getOpenFileSlice asserts that the map size passed in
isn't -1 (presumably because the offset can be nonzero). Switch to
getOpenFile, which results in an identical call to the implementation

Previously, each thread was assigned a fixed list of work, and the main
thread would block until every thread was finished, leading to most
cores sitting idle for the last few hundred milliseconds while a few
particularly long running threads would keep working. Use a single work

* changes:
versioner: use a virtual filesystem for input files.
versioner: cache -cc1 flags generated by the clang Driver.
versioner: refactor to use CompilerInstance directly.
Use an InMemoryFileSystem to store and share input files across
compilations.

Profiling showed that majority of time spent by versioner was being
spent in the x86 and x86_64 driver statting random files in /usr/lib,
looking for a toolchain. Hardcode a list of per-target flags which
correspond to a subset of the ones generated by clang, and use those
instead of calling out to Driver.
This changes the result of `time versioner` from:
versioner 156.57s user 1180.08s system 4109% cpu 32.525 total
to:
