bb-slp-10.c.144t.slp2

Between 20151111 (r230155) and 20151113 (r230309), the gcc.dg/vect/bb-slp-10.c
testcase started to FAIL on Solaris/SPARC, both 32 and 64-bit:

FAIL: gcc.dg/vect/bb-slp-10.c -flto -ffat-lto-objects  scan-tree-dump slp2
"unsupported alignment in basic block."
FAIL: gcc.dg/vect/bb-slp-10.c scan-tree-dump slp2 "unsupported alignment in
basic block."

I'm attaching the dump.
