IIRC, the patch at comment #17 includes the original "lazy creation" of the
external ref. which breaks objc++.
The DWARF fixes are now in trunk, and I have bootstrapped 244409 + comment #20
on darwin12 and x86-64-linux .. so should be posting it soon.

Reproduces on x86_64 with -O -ftree-loop-vectorize -march=corei7 as well.

Ok, so we don't limit group sizes to multiples of nunits which means
vect_transform_slp_perm_load misses an early out. This is then also a missed
optimization as we don't consider the three SLP loads permutes of the single
group load.

PR tree-optimization/66510
* tree-vect-stmts.c (vectorizable_load): Properly compute the
number of vector loads for SLP permuted loads.
* tree-vect-data-refs.c (vect_compute_data_ref_alignment): Also
check the stride for loop vectorization.
(vect_enhance_data_refs_alignment): Deal with SLP adjusted
vectorization factor.
(vect_analyze_group_access): If the group size is not a power
of two require a epilogue loop.
* tree-vect-loop.c (vect_analyze_loop_2): Move alignment
compute and optimizing and alias test pruning after final
vectorization factor computation.
* tree-vect-slp.c (vect_build_slp_tree_1): Remove check on
vector alignment.
(vect_transform_slp_perm_load): Properly compute the original
number of vector load stmts.
* gcc.dg/vect/slp-perm-12.c: New testcase.
