* sysdeps/unix/sysv/linux/i386/lowlevellock.h
(LLL_STUB_UNWIND_INFO_START, LLL_STUB_UNWIND_INFO_END,
LLL_STUB_UNWIND_INFO_3, LLL_STUB_UNWIND_INFO_4): Define.
(lll_mutex_lock, lll_robust_mutex_lock, lll_mutex_cond_lock,
lll_robust_mutex_cond_lock, lll_mutex_timedlock,
lll_robust_mutex_timedlock, lll_mutex_unlock,
lll_robust_mutex_unlock, lll_lock, lll_unlock): Use them.
Add _L_*_ symbols around the subsection.
* sysdeps/unix/sysv/linux/i386/i486/lowlevellock.S: Add unwind info.
* sysdeps/unix/sysv/linux/i386/i486/lowlevelrobustlock.S: Likewise.
