[PATCH 10/10] Remove symbol_get_demangled_name

[Tom Tromey]

Now that symbol_get_demangled_name is only used by general_symbol_info
methods, and because these methods already check the symbol's language
to decide what to return, symbol_get_demangled_name is no longer
needed.  This patch removes it.
