Indeed.  I've also noticed that another regression was caused by the
same change:

XPASS: gcc.dg/vect/slp-multitypes-3.c -flto -ffat-lto-objects=20
scan-tree-dump-times vect "vectorized 1 loops" 1
XPASS: gcc.dg/vect/slp-multitypes-3.c -flto -ffat-lto-objects=20
scan-tree-dump-times vect "vectorizing stmts using SLP" 2
XPASS: gcc.dg/vect/slp-multitypes-3.c scan-tree-dump-times vect "vectorized=
 1
loops" 1
XPASS: gcc.dg/vect/slp-multitypes-3.c scan-tree-dump-times vect "vectorizing
stmts using SLP" 2

Again 64-bit SPARC.=
