This patch introduces two new convenience functions to set the default
thread attributes used for creating threads. This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.
The macros in lowlevellock.h are returning positive errors, but the
users of the macros expect negative. This causes e.g. sem_wait to
sometimes return an error with errno set to -EWOULDBLOCK.

This turns out to be helpful when doing a from-scratch cross-compile of
gcc and glibc, since you can then do "make install-headers" in glibc
even before you have a functioning tile gcc.
Resolves: #15465
The program name may be unavailable if the user application tampers
with argc and argv[]. Some parts of the dynamic linker caters for
this while others don't, so this patch consolidates the check and
fallback into a single macro and updates all users.
The existing test avoided passing -mcmodel=large if the compiler didn't
support it. However, we need to test not just the compiler support, but
also the toolchain (as and ld) support, so make the test more complete.
In addition, we have to avoid using the hwN_plt() assembly operators if
that support is missing, so guard the uses with #ifdef NO_PLT_PCREL.
This allows us to properly build glibc with the current community
binutils, which doesn't yet have the PC-relative PLT operator support.
The -mcmodel=large support is in gcc 4.8, but the toolchain support
won't be present in the community until binutils 2.24.
[BZ #15442] This adds support for the inverse interpretation of the
quiet bit of IEEE 754 floating-point NaN data that some processors
use. This includes in particular MIPS architecture processors; the
payload used for the canonical qNaN encoding is updated accordingly
so as not to interfere with the quiet bit.
Joseph Myers noted that there were several old and really very
incorrect values in the hppa libm-test-ulps. This patch removes
all of the ulps values for ceil, floor, rint, round, trun,
llrint, and llround, all of which were previously incorreclty
added (including some negative values which are really wrong).

* sysdeps/hppa/fpu/libm-test-ulps: Remove old values for ceil, floor,
rint, round, trunc, llrint, and llround.
Update libm-test-ulps for hppa. There are a few entries
with 4 or 5 ulps, but these appear to be expected. A more
thorough review will be required if hppa switches long-double
to a different type.

* sysdeps/hppa/fpu/libm-test-ulps: Regenerate.
The following patch fixes both _FPU_GETCW and
_FPU_SETCW for hppa. The initial implementation was
flawed and not well tested. We failed to set cw,
and passed in the value of a register to fldd.
This patch fixes both of those errors and allows
the libm tests to pass without failure.
