rs6000/test: Support vect_long_long effective target

Currently effective target vect_long_long doesn't have
power specific check, I think it's an oversight.  This
is to add the support which checks for has_arch_pwr8,
since we set rs6000_vector_unit[V2DImode] as:
  (TARGET_P8_VECTOR) ? VECTOR_P8_VECTOR : VECTOR_NONE;
it means its full support starts from ISA 2.07.
Although ISA 2.06 has some instructions like lxvd2x
and stxvd2x etc., it's used for testing, checking for
ISA 2.07 is more sensitive.

gcc/testsuite/ChangeLog:

	* lib/target-supports.exp (check_effective_target_vect_long_long): Add
	support for powerpc*-*-*.
