Align stack to 16 bytes 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.
