The new variant of this PR treats the floating-point locations same as other location. It is more consistent with the current design of memory effects, than a special treatment of the FP locations. It however requires changes in tests, where additional `fpenv: none` may be required. To reduce number of such tests, the changes not necessary to support the new locations are removed.
