0025545: TopLoc_Location::Transformation() provokes data races

Get rid of postponed calculation of transformation.
Remove unused methods.
Add command OCC25545 to reproduce the bug with data races.

- Get rid of C++11 lambda construction
- make code compilable with no HAVE_TBB defined
- add test case bugs/fclasses/bug25545
