[PATCH, rs6000] (v2) testcase updates for fold-vec-abs-* for power9 codegen

[Will Schmidt]

Hi,
    
Add additional scan-assembler entries for those tests with
simple variations in codegen. (for power9, versus power8, etc).

        * fold-vec-abs-char-fwrapv.c: Add xxspltib insn to expected output.
        * fold-vec-abs-char.c: Add xxspltib insn to expected output list.
