* get rid of addr_load_indirect again by having tcgx86 provide an internal implementation of both make_simple_ref() and a_load_ref_reg() so that make_direct_ref() can call the latter (and the latter the former) without fear of inifinite recursive calls due to the symbol; a_load_ref_reg() is additionally declared as "final" as a_load_ref_reg_internal() needs to be overloaded instead (which is the case for tcg8086)
