[PATCH 17/34] rs6000: Add sanity to V2DI_type_node definitions

[Bill Schmidt]

It seems quite strange for these to be "vector long" for 64-bit and
"vector long long" for 32-bit, when "vector long long" will do for both.

	* config/rs6000/rs6000-call.c (rs6000_init_builtins): Change
	initialization of V2DI_type_node and unsigned_V2DI_type_node.
