Change vec_perm checking and expansion level.
The can_vec_perm_p interface changed to use a C integer array. This
allows easy re-use from the rtl level and the gimple level within
the vectorizer. It allows both to determine if a given permutation
is (un-)supported without having to create tree/rtl garbage.
The expand_vec_perm interface changed to use rtl. This allows easy
re-use from the rtl level, so that expand_vec_perm can be used in the
fallback implementation of other optabs.
* target.def (vec_perm_const_ok): Change parameters to mode and
array of indicies.
* doc/tm.texi: Rebuild.
* config/i386/i386.c (ix86_vectorize_vec_perm_const_ok): Change
parameters to mode and array of indicies.
* expr.c (expand_expr_real_2) [VEC_PERM_EXPR]: Expand operands here.
* optabs.c (can_vec_perm_p): Rename from can_vec_perm_expr_p.
Change parameters to mode and array of indicies.
(expand_vec_perm_1): Rename from expand_vec_perm_expr_1.
(expand_vec_perm): Rename from expand_vec_perm_expr. Change
parameters to mode and rtx inputs. Try lowering to QImode
vec_perm_const before trying fully variable permutation.
* optabs.h: Update decls.
* tree-vect-generic.c (lower_vec_perm): Extract array of indices from
VECTOR_CST to pass to can_vec_perm_p.
* tree-vect-slp.c (vect_get_mask_element): Change mask parameter type
from int pointer to unsigned char pointer.
(vect_transform_slp_perm_load): Update for change to can_vec_perm_p.
* tree-vect-stmts.c (perm_mask_for_reverse): Likewise.
