Remove x86 assembler rwlock code

a few cycles near the run-to-run variability). For others it should not

Add adaptive elision to rwlocks
This patch relies on the C version of the rwlocks posted earlier.
With C rwlocks it is very straight forward to do adaptive elision
using TSX. It is based on the infrastructure added earlier
for mutexes, but uses its own elision macros. The macros
are fairly general purpose and could be used for other
elision purposes too.
This version is much cleaner than the earlier assembler based
version, and in particular implements adaptation which makes
it safer.
I changed the behavior slightly to not require any changes
in the test suite and fully conform to all expected
behaviors (generally at the cost of not eliding in
various situations). In particular this means the timedlock
variants are not elided. Nested trylock aborts.

Add a fast path for C rd/wrlock v2
One difference of the C versions to the assembler wr/rdlock
is that the C compiler saves some registers which are unnecessary
for the fast path in the prologue of the functions. Split the
uncontended fast path out into a separate function. Only when contention is
detected is the full featured function called. This makes
the fast path code (nearly) identical to the assembler version,
and gives uncontended performance within a few cycles.
v2: Rename some functions and add space.

get_nprocs: Only return explictly set cache values (BZ #16996)

$ cat nproc.c

#include <time.h>
#include <sys/time.h>
int main(int argc, char *argv[])
{
time_t t;
struct timeval tv = {0, 0};

t = time(NULL);
printf("Time: %d, CPUs: %d\n", (unsigned int)t, get_nprocs());
return 0;

$ gcc -O3 nproc.c
$ ./a.out
settimeofday({0, 0}, NULL) = -1
Time:
1401311578, CPUs: 4
$ sudo ./a.out
settimeofday({0, 0}, NULL) = 0
Time: 0, CPUs: 0
The problem is with the condition used to check whether a cached
value should be returned or not:
static int cached_result;
static time_t timestamp;
time_t now = time (NULL);
time_t prev = timestamp;
atomic_read_barrier ();
if (now == prev)
return cached_result;
This patch fixes the problem by ensuring that 'cached_result' has
been set at least once before returning it.

Remove redundant C locale settings.
Various glibc build / install / test code has C locale settings that
are redundant with LC_ALL=C.
LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C
(explicitly, or through it being in the default environment for
running tests) does not need to set LANG=C. LC_ALL=C also takes
precedence over LANGUAGE, since

* intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE
value is ignored if the selected locale is the C locale.
* intl/tst-gettext.c: Set locale for above change.
* intl/tst-translit.c: Likewise.
and so settings of LANGUAGE=C are also redundant when LC_ALL=C is
set. One test also had LC_ALL=C in its -ENV setting, although it's
part of the default environment used for tests.
This patch removes the redundant settings. It removes a suggestion in
install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the
Makefile.in target "install" already sets LC_ALL_C so there's no need
for the user to set it (and nor should there be any need for the user
to set it).
If some build machine tool used by "make install" uses a version of
libintl predating that 2001 change, and the user has LANGUAGE set, the
removal of LANGUAGE=C from the Makefile.in "install" rule could in
principle affect the user's installation. However, I don't think we
need to be concerned about pre-2001 build tools.

Don't require test wrappers to preserve environment variables, use more consistent environment.
One wart in the original support for test wrappers for cross testing,
as noted in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the
requirement for test wrappers to pass a poorly-defined set of
environment variables from the build system to the system running the
glibc under test. Although some variables are passed explicitly via
$(test-wrapper-env), including LD_* variables that simply can't be
passed implicitly because of the side effects they'd have on the build
system's dynamic linker, others are passed implicitly, including
variables such as GCONV_PATH and LOCPATH that could potentially affect
the build system's libc (so effectively relying on any such effects
not breaking the wrappers). In addition, the code in
cross-test-ssh.sh for preserving environment variables is fragile (it
depends on how bash formats a list of exported variables, and could
well break for multi-line variable definitions where the contents
contain things looking like other variable definitions).
This patch moves to explicitly passing environment variables via
$(test-wrapper-env). Makefile variables that previously used
$(test-wrapper) are split up into -before-env and -after-env parts
that can be passed separately to the various .sh files used in
testing, so those files can then insert environment settings between
the two parts.
The common default environment settings in make-test-out are made into
a separate makefile variable that can also be passed to scripts,
rather than many scripts duplicating those settings (for testing an
installed glibc, it is desirable to have the GCONV_PATH setting on
just one place, so just that one place needs to support it pointing to
an installed sysroot instead of the build tree). The default settings
are included in the variables such as $(test-program-prefix), so that
if tests do not need any non-default settings they can continue to use
single variables rather than the split-up variables.
Although this patch cleans up LC_ALL=C settings (that being part of
the common defaults), various LANG=C and LANGUAGE=C settings remain.
Those are generally unnecessary and I propose a subsequent cleanup to
remove them. LC_ALL takes precedence over LANG, and while LANGUAGE
takes precedence over LC_ALL, it only does so for settings other than
LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C
locale, and anything that gets LC_ALL=C does not need the other
settings.
While preparing this patch I noticed some tests with .sh files that
appeared to do nothing beyond what the generic makefile support for
tests can do (localedata/tst-wctype.sh - the makefiles support -ENV
variables and .input files - and localedata/tst-mbswcs.sh - just runs
five tests that could be run individually from the makefile). So I
propose another subsequent cleanup to move those to using the generic
support instead of special .sh files.

Include LOCPATH in default test environment.
Tests run using the default $(make-test-out) automatically get
GCONV_PATH and LC_ALL set, whether or not those environment variables
are actually needed for the individual test. However, they do not get
LOCPATH set, meaning that a large number of tests have -ENV settings
just to set LOCPATH.
This patch moves LOCPATH into the default environment used for all
tests, on the principle that like GCONV_PATH any settings needed to
use files associated with the newly built library, rather than any old
installed files, are appropriate to use by default.
A further motivation is that various tests using .sh files also set
some combination of LC_ALL, GCONV_PATH and LOCPATH. Preferably .sh
files should also use the default environment with any additions
required for the individual test. Now, it was suggested in
<https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that
various Makefile variables used in testing should be derived by
composing the -before-env and -after-env variables used when explicit
environment settings are required. With such a change, it's also
natural for those variables to include the default settings (via some
intermediate makefile variable also used in make-test-out).
Because some .sh files only set variables that correspond to the
default settings, or a subset thereof, and this applies to more of the
.sh files once LOCPATH is in the default settings, doing so reduces
the size of a revised version of
<https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts
only needing the (expanded) default settings will not need to receive
the separate -before-env and -after-env variables, only the single
variable they do at present. So moving LOCPATH into the default
settings can reduce churn caused by subsequent patches.
