Rafael Espindola 17b1c795d6 Make computeSymbolSizes never fail.
On ELF that was already the case since getting the size of a symbol
never fails.

On MachO and COFF we could fail trying to get the section of a symbol. But
we don't really need the section, just the section number to know if two
symbols are in the same section or not.
