f0f66c0264 Have stdatomic.h punt to C++ atomic when possible
This is an alternate, somewhat simpler, fix that makes it safe to
include both <atomic> and <stdatomic.h> from C++ code in either order.
It means that C code consistently uses one implementation of atomics
and C++ another.  We still have to make sure that those two
implementations interoperate correctly at runtime; in particular,
any flavor of atomic object needs to be represented exactly like the
underlying type, with the proper alignment constraint.

72d7e667c7 Fix our x86 PIC_PROLOGUE.
The old definition only worked for functions that didn't use numbered
local labels. Upstream uses '666' not only as some kind of BSD in-joke,
but also because there's little likelihood of any function having
labels that high.

There's a wider question about whether we actually want to go via the
PLT at all in this code, but that's a question for another day.

Clean up the x86/x86_64 assembler. The motivator (other than reducing
confusion) was that asm.h incorrectly checked PIC rather than __PIC__.

Christopher Ferris
18d93f2793 Do a second key cleanup in pthread_exit.
During pthread_exit, the keys are cleaned. Unfortunately, a call to
free occurs after the cleanup and the memory for some of the keys
is recreated when using jemalloc. The solution is to do the key
cleanup twice.

Also, modify the pthread_detach__leak test to be less flaky
when run on a jemalloc system.

90cb5ffb85 Fix the tzdata update tools.
The recent libcore ZoneInfo changes mean that we can no longer
compile libcore's ZoneInfo against the RI. Luckily, the field in
our data file that we needed ZoneInfo for isn't actually used.
This change removes our dependence on libcore.

I've left the field in to avoid a file format change. We can remove
the field if/when we next have a real need to bump the file format.

From the release notes:

  Changes affecting future time stamps

    Russia will subtract an hour from most of its time zones on
    2014-10-26 at 02:00 local time.  (Thanks to Alexander Krivenyshev.)
    There are a few exceptions: Magadan Oblast (Asia/Magadan) and
    Zabaykalsky Krai are subtracting two hours; conversely, Chukotka
    Autonomous Okrug (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka),
    Kemerovo Oblast (Asia/Novokuznetsk), and the Samara Oblast and the
    Udmurt Republic (Europe/Samara) are not changing their clocks.  The
    changed zones are Europe/Kaliningrad, Europe/Moscow,
    Europe/Simferopol, Europe/Volgograd, Asia/Yekaterinburg, Asia/Omsk,
    Asia/Novosibirsk, Asia/Krasnoyarsk, Asia/Irkutsk, Asia/Yakutsk,
    Asia/Vladivostok, Asia/Khandyga, Asia/Sakhalin, and Asia/Ust-Nera;
    Asia/Magadan will have two hours subtracted; and Asia/Novokuznetsk's
    time zone abbreviation is affected, but not its UTC offset.  Two
    zones are added: Asia/Chita (split from Asia/Yakutsk, and also with
    two hours subtracted) and Asia/Srednekolymsk (split from
    Asia/Magadan, but with only one hour subtracted).  (Thanks to Tim
    Parenti for much of the above.)

  Changes affecting past time stamps

    China's five zones have been simplified to two, since the post-1970
    differences in the other three seem to have been imaginary.  The
    zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been
    removed; backwards-compatibility links still work, albeit with
    different behaviors for time stamps before May 1980.  Asia/Urumqi's
    1980 transition to UTC+8 has been removed, so that it is now at
    UTC+6 and not UTC+8.  (Thanks to Luther Ma and to Alois Treindl;
    Treindl sent helpful translations of two papers by Guo Qingsheng.)

    Some zones have been turned into links, when they differed from
    existing zones only for older UTC offsets where the data were likely
    invented.  These changes affect UTC offsets in pre-1970 time stamps
    only.  This is similar to the change in release 2013e, except this
    time for western Africa.  The affected zones are: Africa/Bamako,
    Africa/Banjul, Africa/Conakry, Africa/Dakar, Africa/Freetown,
    Africa/Lome, Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome,
    and Atlantic/St_Helena.  This also affects the
    backwards-compatibility link Africa/Timbuktu.  (Thanks to Alan
    Barrett, Stephen Colebourne, Tim Parenti, and David Patte for
    reporting problems in earlier versions of this change.)

    Asia/Shanghai's pre-standard-time UT offset has been changed from
    8:05:57 to 8:05:43, the location of Xujiahui Observatory.  Its
    transition to standard time has been changed from 1928 to 1901.

    Asia/Taipei switched to JWST on 1896-01-01, then to JST on
    1937-10-01, then to CST on 1945-09-21 at 01:00, and did not observe
    DST in 1945.  In 1946 it observed DST from 05-15 through 09-30; in
    1947 from 04-15 through 10-31; and in 1979 from 07-01 through 09-30.
    (Thanks to Yu-Cheng Chuang.)

    Asia/Riyadh's transition to standard time is now 1947-03-14, not
    1950.

    Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not
    10-03 at 00:00.  (Thanks to Konstantin Hyppönen.)

    Pacific/Pago_Pago has been changed from UTC-11:30 to UTC-11 for the
    period from 1911 to 1950.

    Pacific/Chatham has been changed to New Zealand standard time plus
    45 minutes for the period before 1957, reflecting a 1956 remark in
    the New Zealand parliament.

    Europe/Budapest has several pre-1946 corrections: in 1918 the
    transition out of DST was on 09-16, not 09-29; in 1919 it was on
    11-24, not 09-15; in 1945 it was on 11-01, not 11-03; in 1941 the
    transition to DST was 04-08 not 04-06 at 02:00; and there was no DST
    in 1920.

    Africa/Accra is now assumed to have observed DST from 1920 through
    1935.

    Time in Russia before 1927 or so has been corrected by a few seconds
    in the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi,
    Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg,
    Europe/Helsinki, and Europe/Riga.  Also, Moscow's location has been
    changed to its Kilometer 0 point.  (Thanks to Vladimir Karpinsky for
    the Moscow changes.)
