Implement interleave via permutation.
* expr.c (expand_expr_real_2) [VEC_EXTRACT_EVEN_EXPR]: Use binop. [VEC_EXTRACT_ODD_EXPR, VEC_INTERLEAVE_HIGH_EXPR]: Likewise. [VEC_INTERLEAVE_LOW_EXPR]: Likewise. * optabs.c (expand_binop): Implement vec_interleave_high_optab, vec_interleave_low_optab, vec_extract_even_optab, vec_extract_odd_optab with expand_vec_perm. (can_vec_perm_for_code_p): New. * optabs.h: Update. * tree-vect-data-refs.c (vect_strided_store_supported): Allow for fallback via can_vec_perm_for_code_p. (vect_strided_load_supported): Likewise. * tree-vect-generic.c (expand_vector_operations_1): Never lower VEC_INTERLEAVE_HIGH_EXPR, VEC_INTERLEAVE_LOW_EXPR, VEC_EXTRACT_EVEN_EXPR, VEC_EXTRACT_ODD_EXPR. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@180450 138bc75d-0d04-0410-961f-82ee72b054a4
