tree-optimization/116973 - SLP permute lower heuristic and single-lane SLP
When forcing single-lane SLP to emulate non-SLP behavior we need to
disable heuristics designed to optimize SLP loads and instead in
all cases resort to an interleaving scheme as requested by forcefully
doing single-lane SLP.
This fixes the remaining fallout for --param vect-force-slp=1 on x86.
PR tree-optimization/116973
* tree-vect-slp.cc (vect_lower_load_permutations): Add
force_single_lane parameter. Disable heuristic that keeps
some load-permutations.
(vect_analyze_slp): Pass force_single_lane to
vect_lower_load_permutations.
