CompilerArgs: refactor __iadd__
the previous optimizations from 4524088d386d2e2315d8fef6ffedc11d8e9a394a
were not relaly good, and not really scaleable, since only the lookup
was improved. However, the really heavy calls to remove have not been
improved.
With this commit we are refactoring CompilerArgs into a data structure
which does not use remove at all. This works that we are building a pre
and post list, which gets flushed into __container at some point.
However, we build pre and post by deduplicating forward. Later on, when
we are flushing pre and post into __container, we are deduplicating
backwards the list, so we are not changing behaviour here.
This overall cuts off 10s of the efl configuration time. Further more
this improves configure times on arm devices a lot more, since remove
does seem to be a lot slower there. In general this results in the fact
that __iadd__ is not within the top 5 of costly functions in
generate_single_complie.
