S390: Adjust lock elision code after review.
This patch adjusts s390 specific lock elision code after review of the following patches: -S390: Use own tbegin macro instead of __builtin_tbegin. (8bfc4a2ab4bebdf86c151665aae8a266e2f18fb4) -S390: Use new __libc_tbegin_retry macro in elision-lock.c. (53c5c3d5ac238901c13f28a73ba05b0678094e80) -S390: Optimize lock-elision by decrementing adapt_count at unlock. (dd037fb3df286b7c2d0b0c6f8d02a2dd8a8e8a08) The futex value is not tested before starting a transaction, __glibc_likely is used instead of __builtin_expect and comments are adjusted. ChangeLog: * sysdeps/unix/sysv/linux/s390/htm.h: Adjust comments. * sysdeps/unix/sysv/linux/s390/elision-unlock.c: Likewise. * sysdeps/unix/sysv/linux/s390/elision-lock.c: Adjust comments. (__lll_lock_elision): Do not test futex before starting a transaction. Use __glibc_likely instead of __builtin_expect. * sysdeps/unix/sysv/linux/s390/elision-trylock.c: Adjust comments. (__lll_trylock_elision): Do not test futex before starting a transaction. Use __glibc_likely instead of __builtin_expect.
