Make xxsplti*, xpermx, xxeval be vecperm type.

I noticed that the built-functions for xxspltiw, xxspltidp, xxsplti32dx,
xxpermx, and xxeval all used the 'vecsimple' type.  These instructions are
permute instructions (3 cycle latency) and should use 'vecperm' instead.

While I was at it, I changed the UNSPEC name for xxspltidp to be
UNSPEC_XXSPLTIDP instead of UNSPEC_XXSPLTID.

gcc/
	* config/rs6000/vsx.md (UNSPEC_XXSPLTIDP): Rename from
	UNSPEC_XXSPLTID.
	(xxspltiw_v4si): Use vecperm type attribute.
	(xxspltiw_v4si_inst): Use vecperm type attribute.
	(xxspltiw_v4sf_inst): Likewise.
	(xxspltidp_v2df): Use vecperm type attribute.  Use
	UNSPEC_XXSPLTIDP instead of UNSPEC_XXSPLTID.
	(xxspltidp_v2df_inst): Likewise.
	(xxsplti32dx_v4si): Use vecperm type attribute.
	(xxsplti32dx_v4si_inst): Likewise.
	(xxsplti32dx_v4sf_inst): Likewise.
	(xxblend_<mode>): Likewise.
	(xxpermx): Likewise.
	(xxpermx_inst): Likewise.
	(xxeval): Likewise.
