Dynamic BCE (based on induction range analysis)

A rewritten dynamic BCE that uses induction variable analysis
to generate the run-time tests before a loop in order to
eliminate bounds-checks from its body. This CL removes now
obsoleted induction related code inside the BCE module.
Also, the dynamic test generation is placed more strategically,
since we missed a few cases where static analysis does better.

Most significant performance improvements (filtering noise) is about:

Linpack +20%
LU    > +10%
