    d: Fix failing test with 32-bit compiler [PR114434]
    
    Since the introduction of gdc.test/runnable/test23514.d, it's exposed an
    incorrect compilation when adding a 64-bit constant to a link-time
    address.  The current cast to size_t causes a loss of precision, which
    can result in incorrect compilation.
    
            PR d/114434
    
    gcc/d/ChangeLog:
    
            * expr.cc (ExprVisitor::visit (PtrExp *)): Get the offset as a
            dinteger_t rather than a size_t.
            (ExprVisitor::visit (SymOffExp *)): Likewise.
    
    (cherry picked from commit 9ab38952a2033d6d4a8e31c3c4d2ab1a25a406c6)
