When DRE->getDecl() is a BindingDecl, the VD branch is skipped (correctly), but
checkAndEmitLastprivateConditional still executes with a DeclRefExpr pointing
to a BindingDecl. The runtime helper likely expects a VarDecl. Guard the call
the same way you guarded the first linear block at ~line 1960-1975 (wrap both
insert and conditional-check in the if (VD) block).
