  Log Message:
  [lld-macho] Unset ExportDynamic where possible for LTO

By unsetting this property, we are now able to internalize more symbols
during LTO. I compared the output of `-save-temps` for both LLD and
ld64, and we now match ld64's behavior as far as `lto-internalize.ll` is

(Thanks @smeenai for working on an initial version of this diff!)
