amdgcn: gather/scatter with DImode offsets

The GPU architecture requires SImode offsets on gather/scatter instructions,
but they can also take a vector of absolute addresses, so this allows
gather/scatter in more situations.

gcc/ChangeLog:

* config/gcn/gcn-valu.md (gather_load<mode><vndi>): New.
(scatter_store<mode><vndi>): New.
(mask_gather_load<mode><vndi>): New.
(mask_scatter_store<mode><vndi>): New.
