ff00dc8565 Workaround the GCC "(long)fn -> lfn" optimization bug.
Pass "-fno-builtin-rint -fno-builtin-rintl -fno-builtin-rintf" to avoid
generating self recursions in lrint, lrintl, and lrintf.

(It turns out that this is the only place we're saying __inline in C++.)

b30aff405a Revert "Revert "Lose the hand-written futex assembler.""
The problem with the original patch was that using syscall(3) means that
errno can be set, but pthread_create(3) was abusing the TLS errno slot as
a pthread_mutex_t for the thread startup handshake.

There was also a mistake in the check for syscall failures --- it should
have checked against -1 instead of 0 (not just because that's the default
idiom, but also here because futex(2) can legitimately return values > 0).

This patch stops abusing the TLS errno slot and adds a pthread_mutex_t to
pthread_internal_t instead. (Note that for LP64 sizeof(pthread_mutex_t) >
sizeof(uintptr_t), so we could potentially clobber other TLS slots too.)

I've also rewritten the LP32 compatibility stubs to directly reuse the
code from the .h file.

This reverts commit 75c55ff84e.

6b3beb23d6 Fixes stdatomic.h test to match C11 spec
C11 defines the expected value to atomic_compare_exchange_* as being non-atomic
types. Using an atomic type is a syntax error in clang.

ff03a7aaad Updated ambiguous comment in pthread_mutex_lock.
The comment used the phrase "normal case" when it more specifically refers to the "recursive case," so I changed it to that.

bdca3802c9 Remove unnecessary padding in ucontext_t
- removed extra padding from ucontex_t on x86, x86_64 and mips
- force ucontext_t struct to use 64 bits for the sigmask on all arches
(previsouly wrong since sigset_t on arm and x86 is only 32 bits)
- arm and arm64 continue to use padding to match glibc sigset_t

This brings Bionic on par with the kernel w.r.t ucontext padding.

f6d2ca2696 Expose __srefill for LP64 until we can fix the NDK.
The LP64 has a duplicate copy of part of stdio, and relies
on bionic supplying this part. We should remove the hack from
the NDK, at least for LP64, and then revert this.

Dan Albert
a7821b7121 Use __typeof__() instead of typeof()
typeof() is a gcc builtin and is not always available (such as clang when
-std=c*). Both gcc and clang always expose __typeof__(), so just use that.

Anthony King <anthonydking@slimroms.net> reports that for Grouper the
Nvidia GL blobs need access to __swbuf. This is because the old <stdio.h>
had inline getc and putc implementations that directly referred to these
symbols.
