amdgcn: disable TImode

Browse source 
The TImode support works for moves only, which has worked in most case up
to now, but no longer.

We still need TImode to exist for the instructions that take two DImode
values packed together, but we don't need to advertise this to the middle-end.

gcc/ChangeLog:

	* config/gcn/gcn.c (gcn_scalar_mode_supported_p): Disable TImode.
