[PATCH] Fix ICE in lto_symtab_merge_symbols_1 (PR lto/88004).

[Martin Liška]

Hi.

This is fix for the PR which we cooked with Honza.
He pre-approved that.

Survives regression tests and bootstrap on x86_64-linux-gnu.

I'm going to install it.

        * lto-symtab.c (lto_symtab_merge_symbols_1): Do not call
        lto_symtab_symbol_p as it does checking of transparent alias.
        These needs to be also merged in the function.
