amdgcn: Disallow TImode vector permute
We don't support it and it doesn't happen without vector extensions, so
just remove the unhandled case.
Fixes gcc.dg/pr78575.c failure.
gcc/ChangeLog:
* config/gcn/gcn.cc (gcn_vectorize_vec_perm_const): Disallow TImode.
(cherry picked from commit e7d3414dffc98efc8424818dedac138c99c9ca79)
