The toplevel asms are in a special section: LTO_section_asm — and that section
(enum value) is only used by lto_output_toplevel_asms/lto_input_toplevel_asms.
The output symbols are in symtab->first_asm_symbol(); and all symbols added
there are added through symbol_table::finalize_toplevel_asm(t).
However, if you don't want to stream it out, we could do the following to
prevent it:
