Since RTM intrinsics are supported in GCC 4.9, we can use them in pthread mutex lock elision. * sysdeps/unix/sysv/linux/x86/Makefile (CFLAGS-elision-lock.c): Add -mrtm. (CFLAGS-elision-unlock.c): Likewise. (CFLAGS-elision-timed.c): Likewise. (CFLAGS-elision-trylock.c): Likewise. * sysdeps/unix/sysv/linux/x86/hle.h: Rewritten.
