Revert 81219ff.

Eigen upstream was broken a little while ago, and it seemed to be
the case that we needed a fix for using the LLT factorization on
ARM.

This has been fixed and AFAIK there are no stable eigen releases
with this bug in it.

For full gore, see

In light of the fix, the extra layer of indirection introduced earlier
is not needed and we are reverting to normal programming.
