Object files generally have a "base" address, which is their preferred
address to be loaded into memory (in the sense that if they are loaded
at this address, then no runtime relocation is required). This is often
the lowest address corresponding to that object file, and various other
addresses are expressed relative to this base (relative virtual
addresses (RVAs) in PE/COFF parlor).

All three of our main object file formats already had such a concept
(it's usually needed to implement SetLoadAddress), but it was not
exposed in any way. The motivation for making this public is that the
symbol address in the breakpad format are written relative to this
address.
