Align stack when calling __errno_location
We should align stack to 16 bytes when calling __errno_location. [BZ #18661] * sysdeps/x86_64/fpu/s_cosf.S (__cosf): Align stack to 16 bytes when calling __errno_location. * sysdeps/x86_64/fpu/s_sincosf.S (__sincosf): Likewise. * sysdeps/x86_64/fpu/s_sinf.S (__sinf): Likewise.
