Since about 20151127, the gcc.dg/vect/pr45752.c test FAILs on Solaris/SPARC:

FAIL: gcc.dg/vect/pr45752.c -flto -ffat-lto-objects  scan-tree-dump-times vect
"gaps requires scalar epilogue loop" 0
FAIL: gcc.dg/vect/pr45752.c -flto -ffat-lto-objects  scan-tree-dump-times vect
"vectorized 1 loops" 1
FAIL: gcc.dg/vect/pr45752.c scan-tree-dump-times vect "gaps requires scalar
epilogue loop" 0
FAIL: gcc.dg/vect/pr45752.c scan-tree-dump-times vect "vectorized 1 loops" 1

This is a regression from GCC 5.  I'm attaching the dump.
