Remove dead code and function
Commit Message
The only use of get_alias_symbol is gated by a gcc_unreachable (),
so the following patch gets rid of it.
Bootstrapped and tested on x86_64-unknown-linux-gnu, OK?
Thanks,
Richard.

* cgraphunit.c (symbol_table::output_weakrefs): Remove
unreachable init.
(get_alias_symbol): Remove now unused function.
