[PATCH, rs6000] Fix typo in documentation file.

[Carl Love]

GCC maintainers:

The following patch contains fixes for the GCC documentation file. 
There is a missing space between vector and the type __int128_t in the
second argument of the documented function.  

The patch makes no functional changes to GCC, just fixes a trivial
typo.

No regression testing done.  Please let me know if the patch is
acceptable to apply to mainline.

                  Carl Love
