Nikita SmithandNikita Smith 1bca83610f changed symbol search logic to run in three steps: undefined, weak, 
and anti-dependency weak, allowing linking to proceed only after
symbols from previous step are added to the symbol table

this solves the problem of anti-dependency symbols because they are
searched in libraries if the dependency is unresolved weak symbol

Nikita SmithandRyan Fleury d3dedd8bef simplifying symbol table scopes 
Linker cannot register extern import symbols initially because
the import object files are not available until all other object files are
resolved. To work around this, we create a stub weak symbol and assign
it to each import symbol. This allows linker to proceed. Once the import
object files are generated, linker replaces the stub symbol with
the actual ones from the import objects.
