PR tree-optimization/50031
* targhooks.c (default_builtin_vectorization_cost): Handle
vec_promote_demote.
* target.h (enum vect_cost_for_stmt): Add vec_promote_demote.
* tree-vect-loop.c (vect_get_single_scalar_iteraion_cost): Handle
all types of reduction and pattern statements.
(vect_estimate_min_profitable_iters): Likewise.
* tree-vect-stmts.c (vect_model_promotion_demotion_cost): New function.
(vect_get_load_cost): Use vec_perm for permutations; add dump logic
for explicit realigns.
(vectorizable_conversion): Call vect_model_promotion_demotion_cost.
* config/spu/spu.c (spu_builtin_vectorization_cost): Handle
vec_promote_demote.
* config/i386/i386.c (ix86_builtin_vectorization_cost): Likewise.
* config/rs6000/rs6000.c (rs6000_builtin_vectorization_cost): Update
vec_perm for VSX and handle vec_promote_demote.
