## Summary This PR cuts the number of MFs used in `solve_bicgstab`, saving on memory and LocalCopy operations. In particular, the MFs `ph` and `sh` are removed. ## Additional background This is a follow up to avoid-use-of-s and other PRs to improve `solve_bicgstab`. My own testing has shown that this PR gives the same results as before, but regression testing should be done to verify this in all cases.
