[SECILC] does not seem to filter redundant attributes and rules

I am in the process of a DSSP rewrite, taking a different approach this
time.

However I encountered something that seems suboptimal:

SECILC seems to not filter redundant attributes and rules

Example i have a type attribute and it has rules associated with it.
However, the type attribute is not associated with any types.

I was hoping that SECILC would be smart enough to determine that it
might as well filter both the type attribute as well as the rules
associated with it.

To reproduce:

git clone https://github.com/DefenSec/dssp1-base.git
cd dssp1-base
secilc `ls *.cil`
sesearch -ASCT -s lib.ld_so.read_files_subj_type_attribute policy.30
seinfo -xalib.ld_so.read_files_subj_type_attribute policy.30


Am i expecting the impossible by expecting SECILC to be smart enough to
determine that something is redundant, and that it can be filtered out
until it becomes applicable?
