    r133144 | bonzini | 2008-03-12 11:33:45 -0400 (Wed, 12 Mar 2008)

causes the following test failures (and new XPASS) on powerpc64-linux with both
-m32 and -m64:

FAIL: gcc.dg/vect/vect-strided-store-u16-i4.c scan-tree-dump-times vect
"vectorized 1 loops" 2
FAIL: gcc.dg/vect/vect-vfa-03.c scan-tree-dump-times vect "vectorized 1 loops"
1
XPASS: gcc.dg/vect/vect-vfa-03.c scan-tree-dump-times vect "vectorized 1 loops"
0
FAIL: gcc.dg/vect/slp-21.c scan-tree-dump-times vect "vectorized 4 loops" 1
FAIL: gcc.dg/vect/slp-21.c scan-tree-dump-times vect "vectorizing stmts using
SLP" 2
FAIL: gcc.dg/vect/slp-7.c scan-tree-dump-times vect "vectorized 3 loops" 1
FAIL: gcc.dg/vect/slp-7.c scan-tree-dump-times vect "vectorizing stmts using
SLP" 3

The patch referenced above made a slight change to slp-7.c.
