[PATCH] rs6000: Fix typo on vec_vsubcuq in rs6000-overload.def [PR108396]

["Kewen.Lin" <linkw@linux.ibm.com>]

Hi,

As Andrew pointed out in PR108396, there is one typo in
rs6000-overload.def on built-in function vec_vsubcuq:

  [VEC_VSUBCUQ, vec_vsubcuqP, __builtin_vec_vsubcuq]

"vec_vsubcuqP" should be "vec_vsubcuq", this typo caused
us to define vec_vsubcuqP in rs6000-vecdefines.h instead
of vec_vsubcuq, so that compiler is not able to realize
the built-in function name vec_vsubcuq any more.

Testing is ongoing, since this is obvious I'll commit
this once everything goes well in testing, and then
backport this in a week or so.

BR,
Kewen
