This is what I observed, but I wonder: why do we need this in the first 
place? In what situation do we have an integer on which we need to apply 
a mask to get an address (i.e. from where does this integer come?).

Then maybe we should add this expect_address parameter to both 
dwarf2_evaluate_property and dwarf2_locexpr_baton_eval…
