compiler: add backend type conversion
Tweak Interface_field_reference_expression::do_get_backend to apply an
additional backend type conversion to the returned result. This is
needed due to the fact that the top level type of the expression is a
function descriptor, however the value being manufactured is a pointer
to <thunk-descriptor, value> struct.
