+ * Vector optional opcode tracking.

+ * optional and may not be supported on the host. Thank Intel
+ * for the irregularity in their instruction set.
+ *
+ * The gvec expanders allow custom vector operations to be composed,
+ * generally via the .fniv callback in the GVecGen* structures. At
+ * the same time, in deciding whether to use this hook we need to
+ * know if the host supports the required operations. This is
+ * presented as an array of opcodes, terminated by 0. Each opcode
+ * is assumed to be expanded with the given VECE.
+ *
+ * For debugging, we want to validate this array. Therefore, when
+ * tcg_ctx->vec_opt_opc is non-NULL, the tcg_gen_*_vec expanders
+ * will validate that their opcode is present in the list.
