Daniel Jasper 3863a9d4f9 Revert r314923: "Recommit : Use the basic cost if a GEP is not used as addressing mode"
Significantly reduces performancei (~30%) of gipfeli
(https://github.com/google/gipfeli)

I have not yet managed to reproduce this regression with the open-source
version of the benchmark on github, but will work with others to get a
reproducer to you later today.
