84088310ce Handle AVX saving on x86-64 in interrupted smbol lookups. 
If a signal arrived during a symbol lookup and the signal handler also
required a symbol lookup, the end of the lookup in the signal handler reset
the flag whether restoring AVX/SSE registers is needed.  Resetting means
in this case that the tail part of the outer lookup code will try to
restore the registers and this can fail miserably.  We now restore to the
previous value which makes nesting calls possible.

421665c40a Optimize x86-64 syscall cancellation handling. 
The syscall wrappers had to save and restore the syscall parameter
values and return value when calling the functions to enable/disable
cancellation were called.  Not anymore.  The called functions are
special and don't modify any unexpected registers.

b48a267b8f Preserve SSE registers in runtime relocations on x86-64. 
SSE registers are used for passing parameters and must be preserved
in runtime relocations.  This is inside ld.so enforced through the
tests in tst-xmmymm.sh.  But the malloc routines used after startup
come from libc.so and can be arbitrarily complex.  It's overkill
to save the SSE registers all the time because of that.  These calls
are rare.  Instead we save them on demand.  The new infrastructure
put in place in this patch makes this possible and efficient.

7b7f43bed1 Memory ordering in pthread_mutex_{,timed}lock. 
All commits should have happened before the mutex lock is taken.
Therefore use the _rel variant of the cmpxchg atomic op.

515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi
register.  But this isn't guaranteed.  Hence we reload the register after
the calls.

92618c954f Optimize x86-64 pthread_cond_timedwait.

exception handling functionality of the gcc runtime.

bfdb73e145 Implement pthread_sigqueue. 
The kernel from 2.3.31 on supports the rt_tgsigqueueinfo syscall.
Use it to implement the non-standard extension which, like
sigqueue, can pass additional data to the receiving thread.
