jens 4ba64fdb3b - integrated ITLB and DTLB into pipeline. 
TLB queries come from pipeline if generic PIPE_ITLB or  PIPE_DTLB is true. Cache query is then disabled.
  If generic PIPE_ITLB or  PIPE_DTLB set to false queries come from cache.
  Piped TLB queries are piped translations with latency of two clocks. Piped translation allow physically indexed and physically tagged caches
- reworked PC logic
- prepared for individual BCUs in EX, MEM and WB stage
- changed LTS and LTU generation in ALU
