Convenience of use. Having an index into the symbol table makes it
really simple to check if a symbol is in a kept comdat or not.

The corresponding case in ELF is that a Comdat is represented as a
vector of section indexes, so this is basically a simplification to
the IR case where we don't need the sections.

Cheers,
