Initial support for R8 based tracing of resource access.
This adds R class specific tracing to the enqueuer marking resource
reachable in the model when we read fields in the R class.
We build ir for the R classes in the analysis to extract the assigned
values of both integer fields and array values in stylable arrays.
This setup only works with non final fields in the R classes (outside
of testing) since we otherwise would not get the field reads.
