Log:
PR c++/80916 - spurious "static but not defined" warning.
Nothing can refer to an internal decl with no definition, so we shouldn't
treat such a decl as a possible devirtualization target.
* gimple-fold.c (can_refer_decl_in_current_unit_p): Return false
for an internal symbol with DECL_EXTERNAL.
