Use the IR symbol table for the IR input object
ELF linker shouldn't skip the IR object when searching the symbol table
of an archive element. If linker doesn't know if the object file is an
IR object, it should give LTO plugin a chance to get the correct symbol
table and use the IR symbol table if the input is an IR object.
