Once alias is resolved, this pointer become NULL.

C++ frontend produce same body aliases and extra name aliases for
virtual functions and vtables that are obviously equivalent.
Those aliases are bit special, especially because C++ frontend
visibility code is so ugly it can not get them right at first time
and their visibility needs to be copied from their "masters" at
the end of parsing.

by an toplevel asm statement).

Like FORCE_OUTPUT, but in the case it is ABI requiring the symbol to be
exported. Unlike FORCE_OUTPUT this flag gets cleared to symbols promoted
to static and it does not inhibit optimization.

Linked list of symbols with the same asm name. There may be multiple
entries for single symbol name during LTO, because symbols are renamed
only after partitioning.
Because inline clones are kept in the assembler name has, they also produce
duplicate entries.
There are also several long standing bugs where frontends and builtin
code produce duplicated decls.
