IFN: Implement IFN_VEC_SET for ARRAY_REF with VIEW_CONVERT_EXPR
This patch enables transformation from ARRAY_REF(VIEW_CONVERT_EXPR) to
VEC_SET internal function in gimple-isel pass if target supports
vec_set with variable index by checking can_vec_set_var_idx_p.
gcc/ChangeLog:

(gimple_expand_vec_cond_exprs): Rename to ...
(gimple_expand_vec_exprs): ... this and call
gimple_expand_vec_set_expr.
* internal-fn.c (vec_set_direct): New define.
(expand_vec_set_optab_fn): New function.
(direct_vec_set_optab_supported_p): New define.
* internal-fn.def (VEC_SET): New DEF_INTERNAL_OPTAB_FN.
