re PR testsuite/46230 (several vectorization tests FAIL or XPASS on SPARC)

	PR testsuite/46230
	* gcc.dg/vect/vect-peel-1.c (main): Prevent initialization loop from
	being vectorized.  Adjust dg-final pattern.  Remove XFAIL.
	* gcc.dg/vect/vect-peel-2.c (main): Likewise.
	* gcc.dg/vect/vect-peel-4.c (main): Prevent initialization loop from
	being vectorized.  Adjust dg-final pattern.
