This is needed to make L work correctly, and bionic tests pass
again, after applying the equivalent of
commit
00aaea364501b3b0abe58dae461136159df1e356 there.
It makes the preexisting code that uses __sync implementations
much more useful, although we should no longer be exercising that
code in AOSP.
Specifically fixes:
We were invoking __has_extension and __has_builtin for GCC compilations.
They're clang specific. Restructured the tests.
The __sync implementation was not defining the LOCK_FREE macros.
ATOMIC_VAR_INIT was using named field initializations. These are a
C, not C++, feature, that is not supported by g++ 4.6.
The stdatomic bionic test still failed with 4.6 and glibc with our
questionable LOCK_FREE macro implementation. Don't run that piece
with 4.6.
In L, this is a prerequisite for fixing:

We already had the POSIX strerror_r, but some third-party code defines

have liked to have written.

Ignore all __weak_alias in OpenBSD libC.
GCC assembler allows xyz to be redeclared as weak,
by __weak_alias(xyz, _xyz), while _xyz is undefined.
Clang does not like that but silently generates no code.
It will reject its own .s file if the assembly code is saved first.
Since we have no reason to define xyz or _xyz as weak symbol now,
and _xyz is a macro to xyz, we simplify libC to have only
xyz defined as global.

Use the default unwind code.
This speeds up the debug malloc code by using the original unwinding code.
The only catch is that it has to link in the libc++ arm unwind code or
there will be crashes when attempting to unwind through libc++ compiled
code.

Undefine _Atomic before redefining
Stdatomic.h was potentially redefining _Atomic, in spite of a
prior definition by <atomic>. This could cause g++ builds that

Fix pthread_getattr_np for the main thread.
Elliott Hughes [Tue, 26 Aug 2014 00:26:50 +0000 (17:26 -0700)]
Fix pthread_getattr_np for the main thread.
On most architectures the kernel subtracts a random offset to the stack
pointer in create_elf_tables by calling arch_align_stack before writing
the auxval table and so on. On all but x86 this doesn't cause a problem
because the random offset is less than a page, but on x86 it's up to two
pages. This means that our old technique of rounding the stack pointer
doesn't work. (Our old implementation of that technique was wrong too.)
It's also incorrect to assume that the main thread's stack base and size
are constant. Likewise to assume that the main thread has a guard page.
The main thread is not like other threads.
This patch switches to reading /proc/self/maps (and checking RLIMIT_STACK)
whenever we're asked.

Fix, generalize stdatomic.h; improve test.
We seem to use this stdatomic.h sometimes, and slightly different prebuilts
at other times, making them all difficult to test, and making it unclear
which one we're testing. This generalizes the bionic header so that it
can be used directly as the prebuilt header as well. So long as they
don't diverge again, that should somewhat improve test coverage.
Use the correct builtin for atomic_is_lock_free.
Fix atomic_flag_init.
Turn on atomic tests even with __GLIBC__, since they now appear to pass.
Include uchar.h in stdatomic.h where needed.
Add a basic memory ordering test.
Fix bit-rotted comments in bionic tests makefile.
