rename member variable for clarity

it's a little strange how the resolver takes an arbitrary intermediate
in it's constructor. Really this should be an 'options' object that
holds the various resolve/remapping options which are read from this
intermediate.
At least for now rename it so it's more clear it's used differently from
other intermediates that are accessed in the resolver (such as the per
stage ones).
