Florian Hahn 99809f98d7 [SCCP] Do not mark unknown loads as overdefined. 
For tracked globals that are unknown after solving, we expect all
non-store uses to be replaced.

This is a follow-up to f8045b250d80, which removed forcedconstant.

We should not mark unknown loads as overdefined, as they either load
from an unknown pointer or an undef global. Restore the original logic
for loads.
