[lld-macho][rfc] Have Symbol::getVA() return a non-relative virtual address

Authored by int3 on Apr 14 2020, 4:47 PM.



Currently, getVA() returns a virtual address with the assumption that
the ImageBase is zero. As I understand, this is what lld-ELF is doing.
However, under our current design, it seems like an awkward setup --
I'm finding that I have to add and subtract ImageBase in several places
to make things work out.

As such, I think it's simpler to have getVA() return a non-relative VA,
but I'm not sure if I'm missing something. Would love to hear more from
folks familiar with lld-ELF.

I'm in favor of this, since it makes the VA actually be a VA and not an RVA :)

This one needs to be properly stacked, I think.
