[dsymutil] Allow debug map mappings with no object file address. NFC

This change just changes the data structure that ties symbol names,
object file address and linked binary addresses to accept mappings
with no object file address. Such symbol mappings are not fed into
the debug map yet, so this patch is NFC.
A subsequent patch will make use of this functionality for common
symbols.
