[PATCH, rs6000] Updates for vec_abs() gimple-folding vector tests

Hi, Assorted testcase updates to handle codegen variations between P7,p8,p9. This breaks out the tests into p7,p8,p9 -specific versions of the same. Sniff-tested on multiple systems, this clears up multiple errors currently seen on P9. OK for trunk? Thanks -Will [testsuite] 2018-01-2
