[COMMITTED PATCH] x86_64: Remove useless pthread_spin_{init,unlock} wrapper files.

[Roland McGrath]

These files served no purpose, as those were the next choices anyway.

	* nptl/sysdeps/unix/sysv/linux/x86_64/pthread_spin_init.c: File removed.
	* nptl/sysdeps/unix/sysv/linux/x86_64/pthread_spin_unlock.S: Likewise.
