objtool: Refactor function alias logic - Add an alias check in validate_functions(). With this change, aliases no longer need uaccess_safe set. - Add an alias check in decode_instructions(). With this change, the "if (!insn->func)" check is no longer needed. - Don't create aliases for zero-length functions, as it can have unexpected results. The next patch will spit out a warning for zero-length functions anyway.
