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.
