* tree-vect-loop-manip.c (rename_variables_in_bb): Add argument
to allow renaming of PHI arguments on edges incoming from outer
loop header, add corresponding check before start PHI iterator.
(slpeel_tree_duplicate_loop_to_edge_cfg): Introduce new bool
variable DUPLICATE_OUTER_LOOP and set it to true for outer loops
with true force_vectorize. Set-up dominator for outer loop too.
Pass DUPLICATE_OUTER_LOOP as argument to rename_variables_in_bb.
(slpeel_can_duplicate_loop_p): Allow duplicate of outer loop if it
was marked with force_vectorize and has restricted cfg.
(slpeel_tree_peel_loop_to_edge): Do not rename exit PHI uses in
inner loop.
* tree-vect-data-refs.c (vect_enhance_data_refs_alignment): Do not
do peeling for outer loops.
gcc/testsuite/
* gcc.dg/vect/vect-outer-simd-2.c: New test.
