[PATCH, rs6000] Testcase fix-ups for gimple-folding intrinsic tests.

[PATCH, rs6000] Testcase fix-ups for gimple-folding intrinsic tests.

[Will Schmidt]

Hi,
  Some testcase fix-ups affecting the gimple-folding tests, including:
- Add xxspltib as a valid instruction for vec-abs tests (power9).
- Fix up mismatched dg-require and dg-option values for the
fold-vec-shift-left-longlong tests (fixes/eliminates a test failure on p6).
    
Sniff tested across P6,P8,P9.
    
OK for trunk?
Thanks,
-Will

	* gcc.target/powerpc/fold-vec-abs-short-fwrap.c: Add xxspltib to
	scan-asembler valid instructions list.
	* gcc.target/powerpc/fold-vec-abs-short.c: Same.
	* gcc.target/powerpc/fold-vec-shift-left-longlong.c: clean up
	power8-vector requirement and option.
	* gcc.target/powerpc/fold-vec-shift-left-fwrapv.c: Same.

This looks fine, okay for trunk, thanks!  One typo:
