The function jit_type_create_struct() defines a struct type. The
function jit_type_get_size() returns the size of the type. You can
allocate the required memory somewhere. Then to compile a code that
accesses a field of the struct you need to have a jit_value_t with the
struct address and then use jit_insn_load_relative() and
jit_insn_store_relative() functions together with
jit_type_get_offset().
