rs6000: Don't call movsi_from_sf in 32 bit mode.

movsi_from_sf uses rldimi instruction, which will cause the compiler to ICE
in 32 bit mode.  This patch limits the recently added pattern and call to
TARGET_POWERPC64.

	* config/rs6000/rs6000.md (rotldi3_insert_sf): Add TARGET_POWERPC64
	condition.
	* config/rs6000/rs6000.c (rs6000_expand_vector_init): Add
	TARGET_POWERPC64 requirement to TARGET_P8_VECTOR case.
